...PERCENTAGES: THE MOST USEFUL STATISTICS EVER INVENTED Thomas R. Knapp © 2010 "Eighty percent of success is showing up." - Woody Allen “Baseball is ninety percent mental and the other half is physical.” - Yogi Berra "Genius is one percent inspiration and ninety-nine percent perspiration." - Thomas Edison Preface You know what a percentage is. 2 out of 4 is 50%. 3 is 25% of 12. Etc. But do you know enough about percentages? Is a percentage the same thing as a fraction or a proportion? Should we take the difference between two percentages or their ratio? If their ratio, which percentage goes in the numerator and which goes in the denominator? Does it matter? What do we mean by something being statistically significant at the 5% level? What is a 95% confidence interval? Those questions, and much more, are what this book is all about. In his fine article regarding nominal and ordinal bivariate statistics, Buchanan (1974) provided several criteria for a good statistic, and concluded: “The percentage is the most useful statistic ever invented…” (p. 629). I agree, and thus my choice for the title of this book. In the ten chapters that follow, I hope to convince you of the defensibility of that claim. The first chapter is on basic concepts (what a percentage is, how it differs from a fraction and a proportion, what sorts of percentage calculations are useful in statistics...

...Abstract Abstract The goal of this master’s thesis is to identify and evaluate data mining algorithms which are commonly implemented in modern Medical Decision Support Systems (MDSS). They are used in various healthcare units all over the world. These institutions store large amounts of medical data. This data may contain relevant medical information hidden in various patterns buried among the records. Within the research several popular MDSS’s are analysed in order to determine the most common data mining algorithms utilized by them. Three algorithms have been identified: Naïve Bayes, Multilayer Perceptron and C4.5. Prior to the very analyses the algorithms are calibrated. Several testing configurations are tested in order to determine the best setting for the algorithms. Afterwards, an ultimate comparison of the algorithms orders them with respect to their performance. The evaluation is based on a set of performance metrics. The analyses are conducted in WEKA on five UCI medical datasets: breast cancer, hepatitis, heart disease, dermatology disease, diabetes. The analyses have shown that it is very difficult to name a single data mining algorithm to be the most suitable for the medical data. The results gained for the algorithms were very similar. However, the final evaluation of the outcomes allowed singling out the Naïve Bayes to be the best classifier for the given domain. It was followed by the Multilayer Perceptron and the C4.5. Keywords: Naïve Bayes, Multilayer...

Consumers’ satisfaction There are two sides in a market for a good DEMAND SUPPLY Created by Consumers Created by firms Each consumer maximizes Each firm maximizes its satisfaction (“utility”) profits ------------------------------- ------------------------------ CONSUMPTION THEORY PRODUCTION THEORY 1 We will first study consumption and later production. In the third part of the course we will take the “demand” schedule from the consumption analysis and the “supply” schedule from the production analysis and put them together in a market. The price, and the quantity exchanged will be determined in the market. We will also discuss the performance and efficiency of markets. A. CONSUMPTION ANALYSIS UNDER CERTAINTY 1. Goods are products or services that consumers or businesses desire. Examples: a book, a telephone call, insurance coverage. Goods may be directly desired by consumers or may contribute to the production of other goods that are desired by consumers. For example a machine used in the production of cars is desirable because it is useful in the production of cars, ...

...The Interpretation of Dreams Sigmund Freud (1900) PREFACE TO THE THIRD EDITION Wheras there was a space of nine years between the first and second editions of this book, the need of a third edition was apparent when little more than a year had elapsed. I ought to be gratified by this change; but if I was unwilling previously to attribute the neglect of my work to its small value, I cannot take the interest which is now making its appearance as proof of its quality. The advance of scientific knowledge has not left The Interpretation of Dreams untouched. When I wrote this book in 1899 there was as yet no "sexual theory," and the analysis of the more complicated forms of the psychoneuroses was still in its infancy. The interpretation of dreams was intended as an expedient to facilitate the psychological analysis of the neuroses; but since then a profounder understanding of the neuroses has contributed towards the comprehension of the dream. The doctrine of dream-interpretation itself has evolved in a direction which was insufficiently emphasized in the first edition of this book. From my own experience, and the works of Stekel and other writers, [1] I have since learned to appreciate more accurately the significance of symbolism in dreams (or rather, in unconscious thought). In the course of years, a mass of data has accumulated which demands consideration. I have endeavored to deal with these innovations by interpolations in the text and footnotes. If these additions do...

According to Chief Justice Marshall of USA, “A company is a person, artificial, invisible, intangible, and existing only in the contemplation of the law. Being a mere creature of law, it possesses only those properties which the character of its creation of its creation confers upon it either expressly or as incidental to its very existence”. Another comprehensive and clear definition of a company is given by Lord Justice Lindley, “A company is meant an association of many persons who contribute money or money’s worth to a common stock and employ it in some trade or business, and who share the profit and loss (as the case may be) arising there from.

...C h a p t e r 1 Prewriting GETTING STARTED (OR SOUP-CAN LABELS CAN BE FASCINATING) For many writers, getting started is the hardest part. You may have noticed that when it is time to begin a writing assignment, you suddenly develop an enormous desire to straighten your books, water your plants, or sharpen your pencils for the fifth time. If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader,...
