Time Series Assignment - Essay Example Autocorrelation function (ACF) is the  cross-correlation  of a  signal  with itself. It refers to the similarity between observations as a function of the time lag between them. ACF is a statistical tool for finding repeating patterns, for example the presence of a periodic signal obscured by noise, or may be identifying the  missing fundamental frequency (Box and Jenkins, 1994) in a signal implied by its  harmonic  frequencies.   Just like ACF, PACF plots (Box and Jenkins, 2008) are also commonly used tool for identifying the order of an  autoregressive model. The partial autocorrelation of an AR (p) process is zero at lag  p  +  1 and greater. If the sample autocorrelation plot indicates that an AR model may be appropriate, then the sample partial autocorrelation plot is examined to help identify the order. One looks for the point on the plot where the partial autocorrelations for all higher lags are essentially zero. Placing on the plot an indication of the sampling uncertainty of the sample PACF is helpful for this purpose: this is usually constructed on the basis that the true value of the PACF, at any given positive lag, is zero. If the PACF displays a sharp cut-off while the ACF decays more slowly (i.e., has significant spikes at higher lags), we say that the stationarized series displays an "AR signature," meaning that the autocorrelation pattern can be explained more easily by adding AR terms rather than by adding MA terms. The plots clearly displays a sharp cut-off for the PACF and a significantly reducing value of spikes for the ACF implying that we instead use an AR

In this similar concern, the strategy of CVP analysis is regarded as a tool that is chiefly used for planning as well as making valuable decisions. Moreover, it is considered as a powerful instrument for devising future plans as well as developing strategies for increasing the sale of the products of the company.

Edgar Allan Poes The Tell Tale Heart Essay Example for Free

Edgar Allan Poes The Tell Tale Heart Essay Edgar Allan Poes The Tell Tale Heart relates the story of one mans obsession at the seemingly trifle and otherwise common place prospect of the gaze of anothers eyes. So consumed is this person of his obsession with the eyes belonging to his tenent or landlord that one night he decides to gouge it off, kill its owner, and bury the eyeball in question under the floorboard. Needless to say, Edgar Allan Poe succeeds in exacting yet another dose of terror, dread and trepidation from his readers. The stated sentiments exist partly because of the plot, but largely because of Poes use of visual imagery, characterized by words which harp on the senses as people perceive it.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   These perceptions, the heightened sensations that the narrator, who is in fact, also the murderer in the story, feels    in the extent of the short story is given structure by the way which he proceeds to talk of his victim. He writes first of being alluded to the eye, not being particularly attached to it initially, but describing it with an endearment out of place, and with a distinction which one would not normally employ when referring to something as ordinary as one of the five senses, except perhaps if people were talking about their lovers (which the narrator is not). His interest shifts and evolves as the story progresses. Talk of the eye in question becomes irrational to the point of alarming, and readers know at this point that something ominous is about to ensue. The narrator begins to talk distinctly of the eye as it were a separate entity, separate from that of its owner, the landlord, who he admits of being nothing but kind, and not having mistreated him in any way. His loving and long winded descriptions regarding, and romancing the eye in question, and the person to whom it belongs to culminates in a course of action which brings him to the landlords bedroom in the middle of the night. While in the victims sleep, he decides to take the eye for himself, and he describes it with such loving and final triumph as though it were a destiny and an important task that had long been awaiting fruition, and the time has come for it to bear fruit.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   More than what has already been narrated and told in the plot, the story tells of one mans obsessive longing, his ascension to insanity (or a closely related version of it) because of the pursuit of that longing, and the consummation of the same longing and madness by means of taking matters into his own hands, and literally plucking out from the face of the earth what had been bothering him for so long. Although not the most pleasant of activities, and certainly not the one people would resort to as a matter of routine or principle. But for the narrator, for the person who needed to put an end to this longing, this itch, this gap which need to be filled, it meant the world and more. It meant a sense of triumph. It indulged his senses and satisfied his itch for an irrational but complex need to fill up a gap in his inner being and sanctum. Despite the questionable ethical as well as moral tendency with which he proceeded in committing the crime, to him it was a necessary road to ease and fulfillment. A Poem As It Regards to the Tell Tale Heart True, people are kind and truer still, people are beautiful but beauty exists in fewer instances these days. In smaller and smaller and smaller packages. So come dearest, let us you and me die

What is an Organ Broker? :: Transplants Health Medicine Crime Essays

What is an Organ Broker? A poor man is desperate to make money to feed his family in an undeveloped country. A rich man is sick and needs a kidney transplant in order to survive. He is willing to pay whatever it takes to save his life. A greedy man acts as a middleman, or broker, between the two men and goes home with a profit of thousands of dollars. Organ brokers are most common for organizing kidney transplants and other non-essential organs. However, occasionally organ brokers will bribe the family of a deceased for essential organs such as heart and liver. The ethical question Is the broker being benevolent by making a match to save someone’s life, or is the broker disobeying an ethical code by bribing the poor man for his kidney and charging the rich man to save his own life so that the broker profits? Making a match For a broker to make any money at all, he must first make a match between a willing donor and a needy, rich recipient. The most common organ brokering is for kidneys. Due to the laws in the United States and other highly developed countries, brokering organs is extremely rare. Brokers typically seek out the impoverished in undeveloped countries not only for their willingness to do anything for a small sum of money, but also for the lack of legal regulations and enforcement. After a broker has found a willing donor, tests are run to determine the blood type and specific organ characteristics. A broker will then make a list of his potential donors and their test results. Next a needy recipient must be found and matched with an organ on the list. When a match is found, the donor is contacted and brought to the operation location—typically in a host country where the operation can be done â€Å"behind closed doors† or without being noticed. In the end, the donor goes home with a small sum of money, the recipient is out hundreds of thousands of dollars and the broker and doctor profit greatly, regardless of the operation being a success or failure. Dealing with the ethical issues Under what circumstances do we decide whether it is just to save another human being’s life? Health professionals that question the standards of the brokers fuel the ethical debate.

Julia`S Food Booth After She Borrows Money

A. Julia would make $1150 profit after paying all expenses after the first game. And then she would make $1721.22 for the rest of the games. Since she will be clearing her number of $1000 profit per game, she should lease the booth. B. If she borrows money from a friend she would increase her profit. She would borrow $380.82 from a friend and she will make $571.22 more profit. The factor that constraints her from borrowing even more money is the total area of space that the warming oven can hold of hot dogs, pizza and BBQ sandwiches. C. Yes, this is something she can reasonably do, since she is making a profit of $1721.22 a game $100 would not be hard to pay for some help. And she should definitely do this because she needs to make a total of 784 hot dogs before the game and before half time. D. One thing that could go wrong would be if her friend was unable to help one game and Julia was unable to make all the hot dogs herself. Another thing that could go wrong would be if her costumers were unsatisfied with the taste of food, or if the warming oven were not operating properly and some of the food came out too cold. Customers would be less likely to come back to the booth the next game or again at half time. Even under these uncertainties Julia should lease the booth because she will more than likely have at least an average of over $1000 of profit for the 6 games.

Obsessive-compulsive Behaviors Essay - 1944 Words

Obsessive-Compulsive Behaviors nbsp;nbsp;nbsp;nbsp;nbsp;quot;Compulsivequot; and quot;obsessivequot; have become everyday words. quot;Im compulsivequot; is how some people describe their need for neatness, punctuality, and shoes lined up in the closets. quot;Hes so compulsive is shorthand for calling someone uptight, controlling, and not much fun. quot;Shes obsessed with himquot; is a way of saying your friend is hopelessly lovesick. That is not how these words are used to describe Obsessive-Compulsive Disorder or OCD, a strange and fascinating sickness of ritual and doubts run wild. OCD can begin suddenly and is usually seen as a problem as soon as it starts. nbsp;nbsp;nbsp;nbsp;nbsp;Compulsives (a term for†¦show more content†¦nbsp;nbsp;nbsp;nbsp;nbsp;Senseless thoughts that recur over and over again appearing out of the blue; certain quot;magicalquot; acts are repeated over and over. For some the thoughts are meaningless like numbers, one number or several, for others they are highly charged ideas-for example, quot;I have just killed someone.quot; The intrusion into conscious everyday thinking of such intense, repetitive, and to the victim disgusting and alien thoughts is a dramatic and remarkable experience. You cant put them out of your mind, thats the nature of the obsessions. nbsp;nbsp;nbsp;nbsp;nbsp;Some patients are quot;checkers,quot; they check lights, doors, locks-ten, twenty or a hundred times. Others spend hours producing unimportant symmetry. Shoelaces must be exactly even, eyebrows identical to eachother. A case studied by the well-known art therapist, Judith Aron Rubin, Rubin tells of a young girl named Mary, who suffers from OCD, and how she drives her fellow waitresses frantic because she goes into a tailspin if the salt and pepper she has arranged in a certain order has been moved around. All of the OCD problems have common themes: you cant trust good judgment, you cant trust your eyes that see no dirt, or really believe that the door is locked. You know you have done nothing harmful but in spite of this good sense you must go on checking and counting. nbsp;nbsp;nbsp;nbsp;nbsp;Show MoreRelatedDefinition Of Behavior Modification : Obsessive Compulsive Disorder ( Ocd ) Essay1336 Words   |  6 PagesïÆ'Ëœ Definition of Behavior modification : Behavior modification is the field of psychology concerned with analyzing and modifying human behavior, analyzing means identifying the functional relationship between environmental events and a particular behavior for understanding the reasons of behavior or to determine why a person behaved as he or she did, modifying means developing and implementing procedures to help people change their own behavior, It involves altering environmental events so as toRead MoreAs Good as It Gets: Obsessive Compulsive Disorder1721 Words   |  7 PagesAs Good As It Gets: Obsessive Compulsive Disorder I chose the film â€Å"As Good As It Gets† and to focus on the character Melvin.
