Ethical Nursing Essay Example Essay Example

Moral Nursing Essay Example Paper Moral Nursing Essay Introduction The point of this exposition is to examine a moral issue experienced while on arrangement. The conversation will concentrate because of the key morals hypotheses of deontology and utilitarianism, morals standards of independence, advantage, non-evil and equity on dynamic by and by. It will consider the patients’ and staffs’ qualities and convictions, enactment and expert practice. Classification will be regarded by utilizing a pen name, as per the Nursing and Midwifery Council [NMC] (2008) rules on secrecy. Song, a multi year old woman, was experiencing the menopause and was admitted to the gynecology ward in emergency clinic in the north west of England with side effects of extraordinary lower stomach agony and issues with pee. Following examinations she was determined to have an uterine prolapse which was causing automatic pee misfortune and maintenance, and clogging. An away from of the condition was given by the advisor who prescribed that she experience a hysterect omy to which she concurred in light of the fact that she was in serious torment. While perusing the educated assent papers before theater, Carol made an unequivocal solicitation that she ought not be transfused with blood or blood items even on account of broad blood misfortune following medical procedure. Her purposes behind this were she had a place with a gathering of Jehovah’s witnesses, and it was basically against her convictions. Morals can be characterized as the philosophical investigation of the virtue of human direct and of the guidelines and rules that ought to oversee it. Moral Nursing Essay Body Paragraphs It is the code of conduct considered right particularly that of a specific gathering, individual or calling (Orme-Smith Spicer, 2001). The morals speculations of utilitarianism and deontology are generally unmistakable in social insurance. Utilitarianism, which can be characterized as ‘doing the ethically right occasion in the demonstration of good’ (Winifred Tadd, 1988,) centers around the results of activities, picking those that do least damage. Connecting this in with Carol’s case, if her hysterectomy was to turn out badly and result in noteworthy plasma volume misfortune, a choice would need to be made to her greatest advantage. If she somehow managed to be transfused her life could be spared however her future bliss as a rehearsing Jehovah’s Witness would be antagonistically influenced. Be that as it may, lawfully and morally, Carol is thought to have the option to settle on choices in regards to her own body which ought to be regarded. The NMC (2008) states if this somehow managed to bring about a weakening of wellbeing, or even demise, as far as morals, it is essentially not allowed to conflict with a patient wishes, whatever the expense. As medicinal services experts, we have an obligation of care which we should seek after consistently. Deontology, another morals hypothesis, centers around the rightness or misleading quality of aims or thought processes behind activity, for example, regard for rights, obligations, or standards, instead of the rightness or unsoundness of the results of those activities (Orme-Smith Spicer, 2001). The deontological moral hypothesis was proposed by Immanual Kant, where he puts incredible accentuation on to the obligation of care. He likewise recommended that the standard of regarding self-sufficiency was of most significance. Tune has unmistakably rejected any blood results of any sort, so the obligation of care given is do everything in capacity to settle the circumstance †aside from trans fusion. Being an obligation based hypothesis, deontology would require social insurance experts to adhere to any standards, guidelines, conventions or methodology set somewhere near the National Health Service and trust whether or not this was what the patient needed. It very well may be seen that neither one of the theories regards or works for the patients’ best result so a blend of the two will ordinarily be utilized to help dynamic (Butts, 2005). To make an interpretation of the speculations into training, Beauchamp and Childress (2001) recommend that a morals hypotheses system which incorporates self-sufficiency, value, non-wrathfulness and equity is useful. Self-rule focuses on self-coordinating opportunity and good freedom. It is the appropriate for patients to settle on their own choices and for social insurance experts to regard these consistently, regardless of whether they believe it to be the correct decision for her or not (Kenworthy, 2002). Ditty is a capable di sapproved, multi year old woman, who has been associated with the Jehovah’s Witness convictions and qualities for various years. She is fit for settling on such a choice subsequent to being made totally mindful of the circumstance, including the advantages and disadvantages of her choice. Non-wrathfulness is the commitment to do no mischief. Value, essentially intends to do great, and is having the quality to be benevolent and obliging. After taking a gander at these speculations all in all, there is no uncertainty about a contention between these standards. Numerous ethical issues looked by medical caretakers originate from clashes between commitments created by the standard of regard for self-rule, against commitments produced by the standards of non wrathfulness and usefulness. Rewarding a patient against their particular wishes applies to ditties case. Self-rule can here and there not be regarded, with specific limitations, for example, the desire to act advantageously. I n Carol’s case, this is transfuse if there was no other arrangement during her medical procedure/aftercare, and it would be to benefit Carol, and acting in a path as to not hurt her further (non wrathfulness). The nurse’s job is to help the patient in settling on educated and proper choices, in understanding to their own qualities or ways of life (Chadwick Tadd, 1992). This implies ethically no blood transfusion should occur as it is the patient’s choice that matters and ought to be regarded. Every single clinical intercession, regardless of whether indicative, remedial or for inquire about †can possibly disregard persistent self-governance. (Quiet focused morals, 2006). It is consistently for the patients’ eventual benefits, and in Carol’s case she has put her religion before her potential hazardous medical procedure. This is as yet her decision, and no specialist or attendant should impact her choice in this. There is continually going to be a possible conflict. Another significant patient-focused moral hypothesis is Paternalism. Paternalism is a refusal of self-governance, and a replacement of an individual’s decisions or activity to their benefit (David Jeffrey, 2006). None clinical perspectives to a people life has more effect and centrality to the patient then the ailment/method nearby. Carol’s religion pays a major part in her life and everything encompassing it, I. e. way of life, family, and Doctors have constrained capabilities to empower them to summarize the damages and advantages which acting in helpfulness can cause. The outcomes of Carol getting blood results of any sort without wanting to, would prompt her turning out to be disregarded by her religion, something that clearly is top need and could demolish her life, devastate her ethics and all that she put stock in. The refusal of a lifesaving blood transfusion by a capable grown-up Jehovah’s Witness, bringing about the demise of a pa tient whose life could have been spared is a case of a genuine moral quandary. On the off chance that Jehovah’s Witness patients are compelled to acknowledge a blood transfusion that is in opposition to their convictions, their self-sufficiency as patients is unmistakably shamed. On the off chance that patients bite the dust because of denying this treatment, there is a feeling that â€Å"harm† has been done and that a clinical â€Å"benefit,† usually accessible to other people, was not accessible for these patients (David Jeffrey, 2006). Equity, another vital morals rule, where the underlining commitment is to regard the way that everybody has the option to human services, regardless of what their convictions or qualities, sex, sexual direction or race. This is a moral structure that centers essentially around an individual’s rights dangers being unreasonable to other people, as issues of self-governance may money with standards of equity (Verena Tschudi n, 1992). Alliteratively, equity can be comprehended as far as decency whereby a person’s guarantee to something depends on an ethically pertinent property, for example, need (Fletcher, 1995). Educated assent is an indispensable factor without which the treatment couldn't morally, legitimately or expertly happen. In current practice the accentuation has moved from wellbeing experts being obliged basically to uncover data to patients, to guaranteeing the nature of data uncovered truly empowers the patient to settle on a self-sufficient choice (Fletcher, 1995). The NMC (2008) states that: â€Å"You must guarantee that you gain assent before you start any treatment or care†. There are two principle types of assent †verbal/activity and educated composed assent. These must be solicited before any sort from care or treatment can happen. In Carol’s case, she had rounded out an assent structure, which recorded all the confinements and wellbeing dangers having her a ctivity could involve. It was on this structure the conceivable requirement for blood transfusion happened, and Carol communicated her conviction issues with accepting this treatment if essential. Specialists for the most part feel that regard for the patient’s self-governance necessitates that this desire ought to be complied. They have sound lawful explanations behind this as well, as to direct blood even with refusal by a patient might be unlawful and could prompt lawbreaker and additionally polite procedures. In spite of the fact that Jehovah’s Witnesses can't acknowledge blood, they are available to other clinical techniques (Garnet, 2000). Proceeding onward ,in practicing authority, a social insurance proficient is limited by the psychological capacities act (2005), which says that acting in compliance with common decency implies acting with genuineness, uprightness, and due industriousness. They should take care of the individual who does not have the capacities to act in accordance with some basic honesty towards them. Educated grown-ups who are equipped for understanding news on their hea

Principles of War, Clausewitz and Jomini Essay Example | Topics and Well Written Essays - 750 words

Standards of War, Clausewitz and Jomini - Essay Example It is significant that Clausewitz work argumentatively built; consistently, Clausewitz follows his presentations with sound contentions, which are planned to reinforce the standard being propelled (Clausewitz 1976). Clausewitz work presents fighting as a demonstration of governmental issues and accentuates on the component of war as being increasingly a financial, a mental, and a political challenge. In this way, as far as procedure, Clausewitz work and hypotheses is progressively important contrasted with the speculations by Jomini. Clausewitz works progresses contentions for the most part for the prevalence of utilizing protection. A more clear component of Clausewitz work is its investigation of the utilization of mainstream and fanatic sentiment. In this manner, the differentiating part of these two war scholars is that, for Jomini, his work was concerned increasingly about move, a war-battling capacity broadly utilized in the nineteenth century war zones. Then again, Clausewitz work was in its viewpoint, vital and predominantly centered around the specialty of war. To put it plainly, the components of Jomini’s work were hostile and move sort of war, though the components of Clausewitz work was described for the most part by some coincidence, brutality, and reasons as the key components. These scholars of war each underscored certain fighting standards. We first look the standards progressed by Jomini. To begin with, we should understand that the fighting standards progressed by Jomini, presently alluded to as Jominian standards were generally intended for wars that were battled before under altogether different perspectives about wars and conditions. One of the standards of war that Jomini underscored was the â€Å"line of operation.† According to him, this was a basic fighting guideline, which he arranged as geological obstructions, i.e., normal lines of activity. He alluded to this as the key decisions and regional lines, i.e., how and where to battle. He alluded to this as â€Å"maneuver lines.† furthermore, Jominian standards of fighting were for the most part focused upon the key contention that a powerful and effectively war needed to hold fast to methodology constrained by a few reliable standards (Jomini 2008). These standards concentrated more on the massing of powers, the hostile, and assaulting a foe power that is more fragile at an exceptionally unequivocal point. In contrast with Clausewitz, Jomini saw war as far as lucidity and straightforwardness. He saw war in gallant and individual terms. Clausewitz believed fighting to be a perplexing, terrible undertaking that is constantly under the danger of getting away from human control. Clausewitz saw the war subject in a way reliable with the eighteenth century Romanticism. The fundamental rule of war that Clausewitz work progressed was that the specialty of dynamic and war challenged the propensity

Free Will Philosophy Essay

I unequivocally accept that W.T. Stace is right while contending for the perspective on delicate determinism, otherwise called compatibilism. Stace has faith in compatibilism, which expresses that determinism is valid, however through and through freedom despite everything exists. He assembles the two perspectives by contemplating the meaning of unrestrained choice. Stace asks, â€Å"How would anyone be able to be rebuffed or compensated for their activities in the event that they have no influence over their actions?† That announcement appeared to be amazingly persuading to me in light of the fact that both d’Holbach and Chisholm bolstered one side of the contention. d’Holbach and Chisholm contended that we are either carefully dictated by the laws of nature and material science or that we are not decided, rather being we have the ability to do as we pick. Stace then again, set up the two positions and made them cooperate. He clarified that the laws of nature and material science do affect our decisions, however we do be able to pick what we need to pick when settling on a choice. Outside powers may push on our choice, however we are the ones liable for picking what we need to pick. He powerfully protects his perspective on delicate determinism by clarifying the meaning of choice. He states, â€Å"In request for one to characterize unrestrained choice, one must investigate how the expression is generally used.† The manner in which a thinker deciphers through and through freedom is not the same as the manner in which a typical individual will do as such. Stace characterizes free goes about as acts that are legitimately brought about by a person’s interior contemplations or wants coming straightforwardly from the individual. Not free acts are those that have outside powers pushing an individual to accomplish something a specific route, for example, a danger or mischief. This was totally different from what different logicians have expressed before. By giving instances of through and through freedom, Stace calls attention to that choice unmistakably exists. It wouldn’t bode well with the expectation of complimentary won't to exist since it is perfect with determinism.

A Southern Twist Using Themes of Southern Fiction to Enhance Silver Sparrow by Tayari Jones - Literature Essay Samples

â€Å"Silver Sparrow,† by Tayari Jones, is a story told in the first person by Dana, the narrator, telling a story about her childhood while looking back as an adult. It takes place in Atlanta, Georgia during the 21st century, although specific dates are not known. Dana’s childhood and family life is somewhat rare; her father is a bigamist. Even at a young age, Dana had some understanding of bigamy. Throughout the story, Dana discusses the jealousy she feels for Chaurisse, her sister from her father’s legitimate marriage, even though Dana was born months earlier. Jones’ describes the pivotal interactions between Dana and her parents when they discuss the situation their family experiences. The climax of the story occurs when Dana finds out that she is part of her father’s secret family. Learning this causes Dana to become more jealous of her sister. However, the twist in the story happens when Dana learns why she should not be jealous of her sister. Gwendolyn, Dana’s mother, drives Dana to see Chaurisse and explains that Chaurisse â€Å"†¦was born too early so she has problems† (Jones 983). Gwendolyn tells Dana that Charuisse has no idea she has another sister and that they, Gwendolyn and Dana, are the only two people who know the truth about the situation. This short story is comprised of several layers of traits that make it a work of southern fiction. Silver Sparrow weaves the southern setting into the piece, focuses the story around the relationships within a family, while touching on race and religion. The story  has a twist within the plot that changes ones feelings about the story. This twist is extremely important because it makes â€Å"Silver Sparrow† an exemplary work of recent southern fiction; the greater significance from this story comes from the twist Tayari Jones introduces at the end of the story. This paper will look at the way different characteristics of southern fiction are present within Jones story. The role of setting descriptions, the focus on familial relationships, and the presence of race and religion within the work will be discussed. After, this paper will discuss the significance â€Å"Silver Sparrow† has as a work of southern fiction.   Southern fiction often depicts the southern setting through vivid imagery of flora and fauna, of the farms and rolling hills, and of the animals characters interacted with. Jones places readers in Atlanta, Georgia throughout â€Å"Silver Sparrow† in a different manner. Because this story takes place in the modern south, there story does not have descriptions of landscapes, farms, or dirt roads. The use of landmarks and street names show the modern twist Jones has put on southern fiction. Faulkner in Light in August and As I Lay Dying vividly describes the rural landscapes his characters live within and come across on their journeys and Faulkner and Hogan depict animals in their work to add to the setting of their novels. Jones does not do that. Instead, Jones uses the modern markers of setting to show the changes occurring within the genre of southern Fiction. The â€Å"West End† neighborhood is used to describe an area of Atlanta where â€Å"one sect of the Back-to-Africa movement [was] headquartered† (979). The narrator, Dana, introduces several locations throughout the story: the store where her parents met (â€Å"Davidson’s downtown†) (979), the street her mother turns off of (â€Å"Gordon Road†) and the park across the street from Chaurisse’s school (â€Å"John A. White Park†) (983). While they do not necessarily add anything to the plot of the story, they do add to sense of authenticity of this work.   However, the theme of southern small town gossip is present in the story.  Dana states: â€Å"if you spend any time in beauty parlors, you will hear the tales of new widows surprised at the funeral by the other grieving widow and her five kids† (979). Beauty parlors and barbershops are contemporary staples of communities in the south. They are locations where individuals gather together and are able to gossip among their peers. However, James, Dana’s father, dislikes the gossip that occurs within Atlanta. James says â€Å"Atlanta aint nothing but a country town and everyone knows everybody. You have to learn to keep yourself quiet† (982). James fears that Dana’s comments about Chaurisse and James’ other wife will be spread around town. Like â€Å"The House of Usher† and As I Lay Dying, â€Å"Silver Sparrow† focuses on the relationships within a family. Dana describes the dynamics of her family, as she understood as a child: â€Å"In my mind, Chaurisse was his real daughter. I was just the outside child. With wives, it only mattered who got there first. With daughters, the situation was a bit more textured† (979). This â€Å"textured† relationship between Dana, her father, and his two families is explored throughout this story. Through Dana’s narration, we learn about each character and the past of the family. This first person narration is similar to the narration in As I Lay Dying but we only receive the views of one character instead of numerous. Dana describes the role of her mother within their family dynamic: There are other words, I know, to describe a woman like my mother and when she is tipsy, angry, or sad, she uses them to describe herself: concubine, whore, mistress, other woman. There are just so many and none are fair. And there are nasty words, too, for a person like me, the child of a person like her, but these words were not allowed in the air of our home (Jones 979). Dana does not view her mother as a â€Å"mistress† or â€Å"other woman† but tells readers the way her mother views herself under specific circumstances. Gwendolyn shapes Dana’s point of view about their families relationship even as an adult: â€Å"I have to agree with my mother that a lot of people suffer from a failure of imagination. They think there is only one right way to do things, only one right way to be happy† (980). Throughout the story  Dana defends her mother’s actions. Gwendolyn shakes Dana to make sure she understands that they need to openly communicate. Dana says that the shaking â€Å"wasn’t a big deal† and that â€Å"she shook [Dana] a little bit†¦not enough to scare her† (983). Out of context or without Dana’s narration, readers could view this action as slighly abusive but Dana reassures readers that it was not her mother’s intention. Dana states that â€Å"it’s hard to be a mot her† and she saw herself as â€Å"just a smaller version of† Gwendolyn (983). Dana admires her mother and the strength her mother maintains while living a secret life. Dana’s narration provides information about her feelings of her father. Her father dislikes when Dana calls him â€Å"sir† because it makes him feel like â€Å"an overseer† (981). However, after learing that Dana is the secret child and not Chaurisse, James allows Dana to call him sir. We learn that James gives Dana two-dollar bills when he is proud of her and she receives these after learning that she is the secret (982). We sense James’ guilt for explaining the relationship to Dana and he gives her $6. Additionally, Dana recounts learning she is a secret after her and her father return to the dinner table. Dana thinks to herself â€Å"You are the secret. He’d said it with a smile, touching the top of my nose with the pad of his finger† (982). Replaying James’ actions helps reiterate that he thinks it’s something cute and minor while Dana is troubled by it, replaying the situation over in her head. As readers, we are able to fo rm an opinion of James. Dana does not say that she is mad at her father for the conversation but she replays the action that distrubs her and changes her mood. These depictions of the other characters in â€Å"Silver Sparrow† are very similar to the depictions of characters within As I Lay Dying. Narrators in both stories do not say that they dislike the actions of the other characters but they do specifically continue to comment on specific actions. The Bundren children never say that they think of Anse as a bad person but they do comment on his actions which lead readers to see him in a particular light. Dana admires her mother’s strength and constantly praising her. Conversely, Dana never states that she’s mad at her father. Because she dwells on their conversation and replays his actions, readers are able to form their own view of James because of Dana’s focus. Narrators do not outwardly state which their feelings about other characters but they do comment on actions and support decisions; this is a theme within works of southern Fiction. Themes surrounding race and religion are present within â€Å"Silver Sparrow† but are not reoccurring within the plot of the story. Dana describes her teacher, Miss Russell, as â€Å"a white lady† and â€Å"the only white person [she’d] ever seen† (980). Up until this point in the story, readers are unaware of Dana’s race. Learning that her teacher is the only white person she’s interacted with leads us to infer that Dana and her parents are black. Tensions involving race in the south are also introduced but not explored too heavily in this piece. Dana explains an incident that occurred with her classmate John Marc. He said â€Å"I never been over a nigger-house before† (981). Dana explained that the â€Å"air in the room stopped circulating†¦[she] knew something had gone horribly awry†¦[and she]†¦never saw him again† (981). Even though John Marc said his comment in â€Å"such a polite way,† the emotions an d meaning surrounding the word â€Å"nigger† offended Dana’s mother (981).The inclusion of issues surrounding race add another southern fiction layer to the story.† Like Light in August, Power, â€Å"Desiree’s Baby,† and â€Å"The Appropriation of Cultures,† race plays a part in this story. Although the role of race is greater in the other pieces mentioned, race is clearly a reoccurring theme within works of southern Fiction. Religion is another theme that is constantly present within southern fiction. While there is only one mention of religion in â€Å"Silver Sparrow† it carries a lot of weight because it occurs at the end of the story. After finding out that Chaurisse is unaware that she has a sister, Dana tells her mother â€Å"God knows everything† and her mother replies by saying â€Å"That’s true†¦and so do we† (984). The mentioning of God is important because it comes at the climax of the story. Dana no longer has reason to be jealous of her sister because she’s learned about her disabilities. Unlike her sister, Dana knows about her family’s situation. Religion is important enough within the life of Dana and Gwendolyn for Dana to liken her knowledge of the situation to the knowledge God has. Similarly, race is a large enough piece of southern Fiction for it to be mentioned in this short story twice. Unlike Jones, O’Connor was largely influenced by religion and it was present within the message of her works. Jones uses religion as a way for Dana to synthesize the information she receives at the end of the story. This piece by Tayari Jones follows the plot trajectory of southern fictions. The story has rising action, climax, and falling action but climaxes again. This second climax or â€Å"twist† comes at the end of the piece and changes some of its meaning. It adds something unknown by the readers and characters earlier in the piece. In â€Å"Silver Sparrow† Dana learns that she is the secret child which is the climax. The twist occurs when Dana learns that Chaurisse has health problems and has no idea that Dana exists. We do not learn about Dana’s reactions to this information as a child or as an adult recalling this exchange with her mother. This is similar to the ending of â€Å"Desiree’s Baby† where we learn about the heritage of Desiree’s husband and that is of mixed decent. Without this piece of information , the meaning of the story changes. We sympathize for Desiree because she wrongfully left; she is not the only reason to blame for having a mixed race baby. Additionally, Anse Bundren in As I Lay Dying surprises readers by returning at the end of the novel not only with his new teeth, but with a new Mrs. Bundren which further proves that Anse is selfishly motivated. This twist does not only occur to add additional drama to these stories, it adds deeper meaning to the work. Without the twist that occurs at the end of â€Å"Silver Sparrow†, readers would feel the same way Dana did at the beginning of the story; they would sympathize with Dana because of the relationship she cannot openly have with her father. Readers would also feel torn because of the bigamy that occurs. Since it is something irregular in mainstream society, it would be hard to accept and support the relationships James has with both of his families. The twist, however, allows Dana, and the readers, to feel bad for Chaurisse and her situation instead of feeling bad for Dana. The readers are able to accept the story as strange or different because of the bigamy but no longer feel bad for Dana. While we do not know what happens in the rest of Dana’s life, readers are able to move on after seeing Chaurisse because of the additional information provided. The second climax, or twist, that occurs in southern Fiction also allows readers to see themes within â€Å"Silver Sparrow† and learn lessons. Granted, various stories teach lessons, this piece is not written with an agenda to sway readers to believe in bigamy or support it. By seeing the challenge Dana faces because of her family and then seeing her realize she should not be jealous of Chaurisse, we learn to accept the things we cannot change. Additionally, we learn to not be jealous of others when you do not know their situation. This story teaches acceptance of one’s life and situation. While we’ve learned to ask â€Å"What’s wrong here?† while looking at southern fiction, Tayari Jones uses the nuances of southern Fiction and adds her twist to it. Not only do readers ask â€Å"What’s wrong here?† while reading the story  but these lessons and themes lead readers to ask questions like: What is normal?, What makes a family?, and Sho uld one feel jealous of another without knowing the full story? Because of the many dimensions of southern fiction, readers can take away many lessons and ask questions about their own lives. Works Cited Jones, Tayari. The Outside Child.

The project, which uses the M3 data, replicates the results obtained by the original researchers and confirms the calculations of their study in terms of a SMAPE (Symmetric Mean Percentage Error) analysis. Don’t waste time! Our writers will create an original "A Comparative Analysis Of The Results Finance Essay" essay for you Create order The data was also analysed using an alternative error analysis methodology (ROC Rate of Change) and conclusions drawn on the comparative analysis of the results. In conclusion this study has shown that the findings drawn in the original M3 study did differ from those obtained using the ROC methodology, although there was some general agreement in the context of complexity or otherwise of the forecasting methodologies employed. For example, the ROC methodology showed that one of the top performing methods was the Theta this in agreement with the SMAPE analysis which ranked it as the best overall performing method. Given also that the Theta method is considered as a simple forecasting approach this tends to confirm the conclusions drawn from the original study. As previously mentioned, this study also showed that there were differences in the overall rankings, using the two different methods of comparison, between the 24 different methods used in the original study. This study also showed that there are differences between the published results of the original study and those replicated in this study.

From the important of these forecasts, many forecasting methods have been applied and used. Furthermore, measurement errors had been implied to forecasting methods to determine their performance. In this study, M3-Competition is to be re-analysed and also investigate with ROC (Rate of Change) methodology. M3-Competition was published in 2000, from the researchers at INSTEAD, Paris. Aims The project had explored and been investigated the conclusions and subsequent commentaries from the original M3-Competition and then undertake an analysis, based on the Rate of Change methodology, on the original data sets and draw comparison of the results. Objectives The study would be involved in the tasks as followed Study the work of all M-Competitions and also related previous work Replicate the result of SMAPE (Symmetric Mean Average Percentage Error) introduced in M3-Competition. To undertake the ROC (Rate of Change Methodology) on the M3 data and produce consequent error Compare the variance measurement errors between SMAPE and ROC Conclude on error measurement goodness 2.0 Study of Forecasting Competition 2.1 Previous Studies Early studies on forecasting accuracy, in the context of this report, were started in 1969. At that time, the studies were only based on limited number of methods. In 1979, Makridakis and Hibon expanded the range and scope of such studies. The study compared 111 time series drawn from real-life situations such as business, industry and macro data. Theils U-Coefficient and MAPE (Mean Average Percentage Error) were used as the measures of accuracy. The major conclusion from these studies was that simple methods such as the smoothing method out performed the more sophisticated ones, as reported in M3-Competition by Makridakis et al. (2000, p. 452). However these conclusions conflicted with the accepted views at that time. 2.2 M-Competition Despite the critics, Makridakis continued his argument by introducing M-Competition (1982). This time the number of series was increased by 1001 and also the number of methods increased to 15. In addition different trials of the same method were also tested. Minor changes were made to the general structure of the competition such as the type of series, which changed to macro, micro, industry, demographic. The observations were arranged as 18 for monthly, 8 for quarterly and 6 for yearly. Also additional measurement errors were added, these were Mean Square Errors, Average Rankings and Median of Absolute Percentage errors. From the results, the four conclusions drawn by Makridakis et al. (1982, 2000, p. 452) were: 1. It was not true that statistically sophisticated or more complex methods, out performed simpler methods. 2. The relative ranking of the various methods varied according to the method of accuracy measurement used. 3. The forecast accuracy, when various indivi dual methods are combined, outperforms the individual methods which were the constituent parts of the combined method and the combined methods on the whole did very well in comparison to other methods. 4. The accuracy of each of the various methods depends upon the length of the forecasting horizon involved. At the conclusion of the study, the results were made available to other researchers for the purposes of verification and replication. This showed that:- 1. The calculations contained in the study were verified and found to be correct. 2. The results were also confirmed when other researchers, using the same data sets, employed different methods of measuring the developed results. 3. Other researchers, using different data series, also reinforced, in their results, the validity of such studies. Throughout this period it was still too soon to state that statistically sophisticated methods did not do better than simple methods when there was considerable randomne ss in the data. It was also shown that simple and sophisticated methods could be equally effective when applied to series which exhibited seasonal patterns. 2.3 M2-Competition In 1993, a further attempt was made to measure and develop the accuracy of various forecasting methods in the M-2 Competition (1993). This was constructed on a real time basis with a further five forecasting organisations (the data was provided by four companies and included six economic series). In this more recent study other forecasting methods, such as NaÃÆ'ƒÂ ¯ve 2, single smoothing and Dampen were included. The accuracy measure employed was based on MAPE (mean absolute percentage error). The four companies provided the experts with the actual data of past and present situations (information on the nature and prevailing business conditions was also provided to the experts). Then the participating experts had to provide forecasts for the next 15 months. After a year, the forecasting data was checked against the actual data from the companies. However the conclusions from this study were identical to those drawn from the M-Competition, in that the more sophisticated m ethods did not create more accurate forecasts than the simpler ones. The study also agreed that the conclusions drawn from previous studies were confirmed. 2.4 M3-Competition The M3-Competition (2000), involved more methods, researchers and more time series. The number of time series was extended to 3003. To reduce the demands on data storage it was decided that a minimal number of observations for each type of data would be used: 14 observations for yearly series 16 observations for quarterly series 48 observations for monthly series 60 observations for other Given the source data, the participating experts were asked to develop further forecasts as follows: 6 for yearly 8 for quarterly 18 for monthly 8 for others The given time series data did not include any data containing negative values. Thus it was expected that the submitted forecasted data should also not include negative data. Despite this requirement, it was decided that any negative values received in the forecasted data, would be set to zero. Also seven methods were also added to the submitted data received from those who used neural networks, expert systems an d decomposition to produce their forecasts. Five accuracy measures were used to analyze the data as follows: Symmetric MAPE Average Ranking Median symmetric APE Percentage Better Median RAE From the analysis of the M3- Competition, the conclusions were identical to the previous M-Competitions. However it was recognised that Theata, a new method used in the M3 competition, had out performed all other methods, and performed consistently well across both forecasting horizons and accuracy measures, suggested by Makridakis et al. (2000, p.459) 3.0 Source Data 3.1 Data format The original data came from the M3- Competition which has been provided by INSTEAD. The data was broken down into two parts, which were actual data and forecast data. The actual data was taken from the website of international institute of forecasters (M3-Competition data). This data was given as an xls. file or in an Excel spreadsheet format. Meanwhile the data was broken down into 5 parts, which were titles as Competition, M3 Year, M3 Quart, M3 Month and M3 Other. However the forecast data was provided by Michele Hibon, who was one of the authors of the M3-Competition: results, conclusions and implication. The datas format was in a DAT. file, this meant that the data was needed to be converted into xls. format in order for the forecast data to be compatible with the actual data. 3.2 Actual data As mention previously actual data was provide as an xls. file. This meant that the data could be used into calculation straight away. However the forecast data only provide the last 6 data in yearly, 8 data in quarterly, 18 data in monthly and 8 data in other. Therefore the last of each type of data would only be used. In order to copy the unsynchronised last data repeatedly, Macro tool was utilised. The code (Macro code) was used to move all the data to right hand side of the spread sheet. This meant that the following last data in each category could be easily copy. Macro code For rearrange the actual data of the M3-Competition Yearly data Sub () aa = Range(A1:BA646) For i = 1 To 646 t = 53 For h = 53 To 1 Step -1 rr = aa(i, h) aa(i, h) = Empty If rr Empty Then aa(i, t) = rr t = t 1 End If Next h Next i Range(A1:BA646) = aa End Sub Quarterly data Sub () aa = Range(A1:BZ757) For i = 1 To 757 t = 78 For h = 7 8 To 1 Step -1 rr = aa(i, h) aa(i, h) = Empty If rr Empty Then aa(i, t) = rr t = t 1 End If Next h Next i Range(A1:BZ757) = aa End Sub Monthly data Sub () aa = Range(A1:ET1429) For i = 1 To 1429 t = 150 For h = 150 To 1 Step -1 rr = aa(i, h) aa(i, h) = Empty If rr Empty Then aa(i, t) = rr t = t 1 End If Next h Next i Range(A1:ET1429) = aa End Sub Other data Sub () aa = Range(A1:DF175) For i = 1 To 175 t = 110 For h = 110 To 1 Step -1 rr = aa(i, h) aa(i, h) = Empty If rr Empty Then aa(i, t) = rr t = t 1 End If Next h Next i Range(A1:DF175) = aa End Sub 3.3 Forecasted data Forecasted data consisted of 24 forecasters which were all provided in DAT. file. The data was then converted into xls. file by opening the file through Excel. Also margins were added to separate each of the value to according cells. However the imported data still has data which overlay each other and did not match the format of the actual data. Therefore Macro was used to rearrange data to working format. The data was first rearrange to remove the overlay on each observations by demonstrate an example on macro. Then this was done repeated to set condition on macro. Meanwhile the cells which used to have the overlay values were still present. Therefore another macro was used made to remove all the empty cells. Meanwhile with AAM1 and AAM2 data, condition on macro needed to be changed as only 2184 observations were provided. At last in order for the data to be compatible with the actual data, heading for each observation was then remove by another written macro. Macro code: R earrange the overlay values Sub () For i = 2804 To 8514 Range(A i + 1 :H i + 1).Select Selection.Cut Range(I i).Select ActiveSheet.Paste Range(A i + 2 :H i + 2).Select Selection.Cut ActiveWindow.ScrollColumn = 2 ActiveWindow.ScrollColumn = 3 ActiveWindow.ScrollColumn = 4 ActiveWindow.ScrollColumn = 5 ActiveWindow.ScrollColumn = 6 Range(Q i).Select ActiveSheet.Paste ActiveWindow.ScrollColumn = 5 ActiveWindow.ScrollColumn = 4 ActiveWindow.ScrollColumn = 3 ActiveWindow.ScrollColumn = 2 ActiveWindow.ScrollColumn = 1 i = i + 3 Next i End Sub Remove all the empty cells Sub () j = 5659 For i = 2805 To j Rows(2819:2820).Select Rows(i : i + 1).Select Selection.Delete Shift:=xlUp i = i + 1 j = j 4 Next i End Sub Remove all the heading Sub () j = 3003 For i = 1 To j Rows(2819:2820).Select Rows(i : i).Select Selection.Delete Shift:=xlUp Next i End Sub Macro code (AAM1 and AAM2): Rearrange the overlay value Sub () For i = 1514 To 7224 Range(A i + 1 :H i + 1).Select Selection.Cut Range(I i).Select ActiveSheet.Paste Range(A i + 2 :H i + 2).Select Selection.Cut ActiveWindow.ScrollColumn = 2 ActiveWindow.ScrollColumn = 3 ActiveWindow.ScrollColumn = 4 ActiveWindow.ScrollColumn = 5 ActiveWindow.ScrollColumn = 6 Range(Q i).Select ActiveSheet.Paste ActiveWindow.ScrollColumn = 5 ActiveWindow.ScrollColumn = 4 ActiveWindow.ScrollColumn = 3 ActiveWindow.ScrollColumn = 2 ActiveWindow.ScrollColumn = 1 i = i + 3 Next i End Sub Delete the empty cells Sub () j = 7224 For i = 1515 To j Rows(2819:2820).Select Rows(i : i + 1).Select Selection.Delete Shift:=xlUp i = i + 1 j = j 4 Next i End Sub 3.4 Data source error By dealing with a large data set, errors could have been occurred through out data transfer from the original and tested data. In the process of prepare forecasted data, five forecasts had been found to obtain negative forecasted results. The forecasts are as followed; Robust-Trend Automat ANN Theata ARARMA SmartFcs Also some forecasts had more negative values than other. Robust-Trend was found to have the most number of negative values present in the data, with 151 negative values. The second was Automat ANN, which as the list followed. This meant that the least would be SmartFcs with one negative values presented. Therefore negative values in the five forecast were then replace by positive sign. This was the case as of the reason that the result, which obtained was nearer to result published in M3-Compettiton (2000). Method Number of data Robust-Trend 151 Automat ANN 47 Theata 19 ARARMA 4 SmartFcs 1 Table 1 Number of neg ative data in each forecasting method 4.0 SMAPE (Symmetric Mean Average Percentage Error) Concept and Calculation 4.1 Definition Symmetrical Mean Average Percentage Error (SMAPE) or Adjusted Mean Average Percentage Error, Armstrong (1985) A could be defined as: SMAPE = (1.1) Note: X- Actual value, F Forecasted value, which the sum of the total divided by number of observations Despite the similarity to MAPE (Mean Average Percentage Error), SMAPE had an advantage to Mean Average Percentage Error as this would eliminate the favour for low estimates and also there were no limits to high side, mentioned by Armstrongs Long-Range Forecasting book (1985). Meanwhile the limit of SMAPE was between 0%, which meant for perfect and 200% for infinitely bad forecast. This meant that SMAPE was to be less sensitive than MAPE to measurement errors in actual data, stated by Armstrong (1985, p. 348). However SMAPE was not totally symmetric as over-forecasts and under-forecasts were not treated equally. 4.2 Calculation In each forecast, SMAPE had been done individually according to forecasting horizon. At first, Average Percentage Mean (APE) was calculated according to each observation for 3003 observations and 2184 observations (AAM1 and AAM2) as followed: The calculation of Error, which could be defined as Error = Actual Forecast Take the Absolute Error, | Error | Calculate the sum of Actual and Forecast Divided the sum of Actual and Forecast by 2 Calculate the APE by taken the value in step 2 divided by value in step 4. In order to produced, SMAPE, the sum of value of APE in each observation were divided by the number of observations which it had been considered. Then, the SMAPE was calculated according to boundary forecasting horizon, such as 1 to 4, 1 to 6, 1 to 8, 1 to 12, 1 to 15, and 1 to 18. 4.3 Results From the SMAPE, the forecasts were ranked from best with the least error to worst with the highest. These were ranked according to the result from boundary forecasting horizon 1 to 18. This was the case as the selected error would combine all the errors in 18 forecasting horizons. This was shown in Table 2 and 3: Example result from Theata method Forecasting horizon SMAPE N 1 0.084017 3003 2 0.095669 3003 3 0.113103 3003 4 0.125112 3003 5 0.131298 3003 6 0.139994 3003 7 0.122699 2358 8 0.119834 2358 9 0.131595 1428 10 0.133898 1428 11 0.1347 1428 12 0.132214 1428 13 0.154032 1428 14 0.151862 1428 15 0.162854 1428 16 0.177043 1428 17 0.168029 1428 18 0.182731 1428 Table 2 SMAPE across the 18 forecasting horizons Forecasting Horizon 1 to 4 1 to 6 1 to 8 1 to 12 1 to 15 1 to 18 Total Per centage Error 1254.958 2069.647 2641.54 3401.817 4071.19 4824.892 N 12012 18018 22734 28446 32730 37014 SMAPE 0.104475 0.114866 0.116193 0.119589 0.124387 0.130353 Table 3 SMAPE between 18 forecasting horizons boundaries 4.4 Matching M3-Competition data In order to replicate the result from the M3-Competition, the same SMAPE, which was mention previously, was used as the measurement error on the M3 data. The obtained SMAPE result was then compare to the result published in M3-Competition, which was shown in the table 4.

From the result, some methods seem to out perform better than it was expected. For example, AAM1 had moved up by 5 ranks. Also NaÃÆ'ƒÂ ¯ve2 had out performed Autobox3. Meanwhile, some methods did not perform as well, for example Theata-sm was decreased by 6 ranks. Graph 1 Comparative ranking of SMAPE between published results in the M3-Competition and those calculated in this study Graph 1 Comparative Ranking between M3-Competition and calculated result Graph 2 Matching difference between published results in the M3-Competition and those calculated in this study As mention earlier, some errors had been found in the raw data. These were the negative data in the 5 forecasting me thods. However, as all the negative values was replaced with positive values in these forecasting methods. There were two forecasting methods which produced the corresponded ranking to the original M3 SMAPE analysis. These methods were Robust-trend and Theata. But the rest which were AutomatANN, SmatFcs, and ARARMA, had mis-matched the original SMAPE by 2 ranks. Despite, the argument above, it was clear that there were other forecasting methods which had perfectly good data, produced mis-match result. As the size of the data, it was possible that errors could have occurred in various stages in the calculation, even though this had been treated with caution. For example, rounding errors could occur when the 3003 observations were used to calculate the total SMAPE in each forecasting horizon. This meant that by considered the more number of observations, the likelihood of the errors in rounding would be more noticeable. Also it was to be mention that the forecasted data was not directly obtained from the M3-Competion, as the data was not published in the paper of M3-Competition (2000). Therefore it was fair to that the forecasted data could not have been the identical one which was used in the M3-Competition. However, this data was provided by Michele Hibon. Therefore, despite the difference in result, both results produced the same conclusions and also the data was obtained from a reliable source. This was also proven by the small deviation in the plot of both results, as Root Mean Square value was 0.9012. 5.0 ROC (Rate of Change) Concept and Calculation 5.1 Definition The Rate of change method is based on the Centred Forecast-Observation diagram for change developed by Theil (1958) and subsequently reported by Gilchrist (1976) and extended by John (2004, p.1000). In 1968, the diagram of actual and predicted changes was a graphical picture of turning point error, mentioned by Theil (1958, p. 29). This was represented on the horizontal axis as actual change, vertical axis as predicted change (observation change), and with a line of perfect forecast which was 45 ° to the origin. The diagram is divided into four quadrants, the second and fourth quadrants represent turning point errors. These are determined by the sign of the preceding actual change in the same variable. Meanwhile, the other two quadrants were divided by the line of perfect forecast into equal areas of overestimation and underestimation of changes. Centred Forecast-observation diagram, Gilchrist (1976 p. 223) was used to explain more about the characteristics of forecasting. The diagram is split into six quadrants. This was also mentioned by John (2004, p. 1001). John (2004) uses the diagram as a chart with the forecast series on the y-axis and actual series on the x-axis. For each actual series a pair would be determined as: Z/Ai = Ai + 1 Ai (2.1) Then for each forecast series the pair would be: Z/Oi = Ôi + 1 Ôi (2.2) Note: A pair of actual values, Ô pair of forecast values Then each of the individual pairs of Z/Ai and Z/Oi could be determined and plotted. As mentioned previously the chart was divided into six quadrants, the quadrants start in a clockwise direction from the forecast pair axis in positive. The quadrants are as follows: Sector 1 Overestimate of positive change Sector 2 Underestimate of positive change Sector 3 Forecast decrease when an increase in the actual occurs Sector 4 Overestimate of negative change Sector 5 Underestimate of positive change Sector 6 Forecast increase when a dec rease in the actual occurs Graph 3 Z/O Z/A chart, by John (2004) In each quadrant the number of errors could then be determined. However, the magnitude of the errors in each quadrant was not as equal as each other. The error was then divided into two distinct types, normal error and quadrant error, as recognised by John (2004). Normal error was given to the pair which had the same direction (sign of change), and measured as: Normal error = (|Z/Ai| | Z/Oi|)  ² (2.3) When the direction (sign of change) of Z/Ai and Z/Oi was different, for example Z/Ai was positive and Z/Oi was negative. This was known as the quadrant error, and measured as: Quadrant error = (3|Z/Ai| + | Z/Oi|)  ² (2.4) This was devised by John (2004), since it could be argued that even if a forecast failed to recognize the correct magnitude of change, it would be expected that it should at least recognise the direction of change. 5.2 Result In each forecasting horizon, all the Z/Ai and Z/Oi were calculated and allocated to correct position on the chart. Then the magnitude of errors in each quadrant was calculated. Then total normal error, total quadrant error, and total error for individual forecasting horizon were calculated, as shown in Single method in table 5. Therefore by adding all the total errors from each forecasting horizons, the total magnitude of error could be determined for each forecast methods.

This became clear as Single out performed all of the selected methods. Single was based on single exponential smoothing, considered to be a simple method. Also the explicit methods, such as Robust-Trend and Winter came last in the competition. Also it was proven that different accuracy measures would produce a different relative ranking of the various methods. By taking a comparative analysis of the two measurement error methods, some forecasting methods did perform better in ROC. An example of a significant change was between Single and NaÃÆ'ƒÂ ¯ve2. These methods improved by 11 ranks when compared with SMAPE. In addition, combined methods did still out perform individual methods. As it showed that Winter, which was explicit trend model did worst in all of the method s. Furthermore, the worst combined method was Flores-Pearce1, which was 19 in ROC and 16 in SMAPE. For all the agreement mentioned above, ROC and SMAPE were still different methods of error measurement and did produce different results. In ROC, errors could be divided into normal and quadrant. This gives the researchers more information on how each forecasting methods did and also indicates where and how improvements could be justified. Also from this extended information of the measurement error, performance on each forecasting horizon in each forecasting methods could be compared against normal and quadrant errors. As mention in the definition of ROC, normal error could be divided into two types, over-estimates and under-estimates. This information would be critical on the improvement of forecasting methods. In this study, the number of error points in each type was calculated. An example of this could be seen in Single (Table A4) and Winter (Table A5) [ROC results] in the a ppendix. From this sample, the table also showed that correct data point were also obtained form the ROC. Despite the advantage of this information, quadrant errors were still the most dominant in magnitude of the calculated error in each forecasting method. As in NaÃÆ'ƒÂ ¯ve 2, which had the most correct data points with 90, still came 11 in the overall rank. Also this could be supported by Winter which had more correct data points and was still overall the worst performance. If the over-estimates and under-estimates are considered and separated into positive change (Sector 1, S1 and Sector 2, S2) and negative change (Sector 4, S4 and Sector5, S5) then further comments could then be made on each individual observation in each forecasting method. Thus it could be argued that despite the fact that SMAPE and ROC produce the same conclusion on the overall performance of the type of forecasting methods, one major difference could be identified. In that it was true to say that ROC could be used as to better understand the errors caused in each forecasting methods. Such analysis is not possible with other methods of error measurement such as SMAPE. The ranking of each of the forecasting methods are listed in table 8: Rank SMAPE ROC 1 Theata Single 2 Forecast Pro Theata 3 Force X Comb S-H-D 4 Comb S-H-D Force X 5 Dampen Flores-Pearce2 6 RBF SmartFcs 7 B-J automatic Theata-sm 8 Automat ANN Dampen 9 SmartFcs Forecast Pro 10 PP-autocast AAM1 11 Flores-Pearce2 NaÃÆ'ƒÂ ¯ve2 12 Single AAM2 13 Theata-sm B-J automatic 14 Autobox2 RBF 15 AAM1 Automat ANN 16 Flores-Pearce1 PP-autocast 17 ARARMA Holt 18 AAM2 Autobox3 19 Holt Flores-Pearce1 20 Winter Autobox1 21 Autobox1 Robust-Trend 22 NaÃÆ'ƒÂ ¯ve2 Autobox2 23 Autobox3 AR ARMA 24 Robust-Trend Winter Table 8 Comparative ranking between SMAPE and ROC Graph 4 Comparative ranking between SMAPE and ROC 7.0 Discussion and Conclusion This study has replicated the results from the M3-Competition, despite some of the mis-matching of the ranking of methods. Also, the Rate of Change (ROC) concept has been introduced as another method of error measurement. From the results of ROC analysis, many characteristics of the forecasting methods have been better understood. In the analysis, AAM1 and AAM2 had seemed to perform better in most of the categories, but when the number of observations was taken into account their true ranking was obtained. After normalising the results to per observation in table 7, Single and Theata did perform as well as expected. Single had the least number of under-estimated errors and Theata had the least number of quadrant errors. However, Robust-trend had the least over-estimates. This was not expected since overall it was one of the worst performing forecasts in both SMAPE and ROC. But, it could be argued that it had presented the most number of under-estimated errors and therefore this mea nt that the total normal errors would be much higher than the other methods. Also from the ROC results per observation, it was evident that AAM1 and AAM2 were the worst methods in over-estimates, under-estimates and quadrants. In ROC analysis, the number of correct forecast could also be accumulated. This showed that NaÃÆ'ƒÂ ¯ve2 had 90 correct values, whilst the others had only 20 correct values. Also the Winter had obtain 1 correct value, thus it was regarded as the worst performer in ROC. However from the results, it was true to say that quadrant values would still be the most dominant on the performance of the forecast. This meant that the higher the quadrant, the less likely for the forecasting method to perform well. For example, NaÃÆ'ƒÂ ¯ve2 had more correct values than Single. But Single did have lesser quadrant values. Therefore Single would out perform Naive2, [see the results recorded by rank, table 8]. Also ROC analysis showed that the resu ltant information could be used to improve the accuracy of forecast. [this was mentioned in the comparative of SMAPE and ROC]. In ROC, the trend of the plot in each forecasting horizon could explain the performance of each method. A good example would be by taking ROC plots of the forecasting horizons from the best and worst methods respectively, [Single and Winter]. The Single plot was taken from the 11th forecasting horizon, and the 9th forecasting horizon was taken from Winter data. By comparing the two plots, the differences in the distribution of errors can be clearly seen. In Single, the data points are mainly distributed in the sectors 1, 2, 4 and 5. This means that the errors which were obtained would under-estimates and over-estimates [normal errors]. Whilst, in Winter a large numbers of data points fell in sector 6, which is quadrant error. This means that a greater error was created from the Winter method than from the Single method. In addition, the Winter plot showed that there were more data points in sectors 1 and 4 than in sectors 2 and 5. This meant that the method tended to over-estimate the forecasts. Also it was still to be noted that there were some minority of under-estimates. Also the same observation could be used on Single plot. There were more data points in sector 1 than sector 2. This meant that the method tended to over-estimate in a positive direction. However, this was different in negative direction since there were more data points in sector 5 than in sector 6. Therefore, the method tended to under-estimate in the negative direction. From these observations, the analysis on each method could be sent back to each forecasting method as advice. Then this could be used to improve the methods for better forecasts in the future. Therefore, it was clear that ROC has a much greater advantage in analysing forecasts than other measurement methods. However, more work is needed to produce an ROC analysis than is required for a SMAPE analysis. Also this means that more care is needed since the calculations increase as the number of forecasting horizons in each forecasting method increases. Conclusion This study has replicated the results of the M3 competition using SMAPE as the means of error measurement and undertaken a further analysis on the same data using the ROC method developed by John (2004). The study has proven that the conclusions of the M3-Compeition are still valid. However, it could be argued that re-analysis of SMAPE was not totally reliable due to some mis-matching in the ranking performance of the original SMAPE in M3-Competition and calculated SMAPE from this study. Also there were data errors found in the source data. In addition as mentioned earlier, rounding error could have occurred in the calculations, [as suggested by Chatfield C. (1988, p. 28) when he said that There are obvious dangers in averaging accuracy across many time series]. Meanwhile, this could be argued that the calculated SMAPE produced the same conclusions as previous SMAPE results in M3-Competition. In addition the same conclusion was also recognised by ROC. This meant that all the res ults tested produced one critical conclusion which was that Simple method did outperform many of the more sophisticated methods, which included individual and combined methods. Also in general, the combined methods did perform better than the individual ones. From this analysis, the use of the Simple method could be now more appreciated since it gave an equal or greater result of accuracy when compared to the more complex forecasting methods. Also this would broaden the uses of the forecasting method, which despite the fact that accuracy was just one indicator of performance beside cost, ease of use, and ease of interpretation. Also this was mentioned by Chatfield (1998, p. 21), that simple methods were considered likely to be easily understood and implemented by managers and other works that used these forecasted results.

Mexico An Elegant And Beautiful Place - 1125 Words

Mexico is an elegant and beautiful place. Its geography is beautiful and diverse. The land holds interesting history. It is rich with culture and delicious food. It also has great works of art. Mexico is rich with resources and It is difficult to count all the great things about Mexico. Mexico gets people to keep returning. This is why many people live in Mexico and prefer it to other places. Mexico is located south of the Americas and north of Guatemala and Beliz. Mexico is bordered on either side by water. The west and south side is covered by the Gulf of California and the Pacific Ocean, while the Gulf of Mexico and the Caribbean Sea border the east. Mexico’s 756,066 square miles contain swamps and lagoons, beaches and tropical rain forests, mountains, volcanos, and dry deserts. More than half of Mexico, mostly around the southern area, is tropics. With Mexico’s diverse climate, there are many different unique ecosystems, each with its own plants and animals. (Jermyn 6-8) Mexico’s people have had a difficult time establishing a stable and dependable government that they support. Spain had control over Mexico, and although many had tried, it was not until August 24, 1821, when the last Spanish viceroy was forced to sign the Treaty of Cà ³rdoba making Mexico independent.
