## Extract of sample "Bayes' Theorem"

Download file to see previous pages Simon Jackman (2009) defines Bayes’ theorem as ‘a theorem that illustrates conditional probability of the set on the given observed outcome, that is obtained from the knowledge of the probability and its outcome (Jackman, 2009)’.
The rules of Bayes’ theorem are based on the basic axioms of probability or conditional probability. It expresses subjective depress of beliefs explaining the repletion through Bayesian statistic fundamental. The mathematical representation of theorem is as follow:
Bayesian statistical method provides in depth understanding about the events. The application of theorem is wide in various fields and subjects, such as, science, biology, mathematics, finance etc. The model is applied to determine relation between the events. In the field of finance the Bayesian method is adopted for financial forecasting. One of the major advantages of Bayesian theorem is the consideration that is given to the previous information. The fact is that many statisticians would disregard previous information in order to prove the objectivity of the current statistics. The Bayesian theorem proves objectivity of the statistics by combining both the sets of information. A very significant advantage noted for the usage of Bayesian theorem is that it provides direct probability statement. This is considerably the best way to interpret confidence interval. On comparison, one can easily find out that frequents statistics would imply a number of tools. On the other hand, Bayesian approach makes use of only one theorem i.e. Bayesian. The fact remains as that Bayesian approach can be used in different situations where most of the tools of frequentist statistics fall short.
In the Bayesian theorem, the conditional probability occur on the bases of unconditional probabilities that are derived using a multiplication rules, that is (Prior x Likelihood) that are further divided by the sum of the possible parameters. Posterior in Bayesian theorem can be identified ...Download file to see next pagesRead More

### First Fundamental Theorem of Welfare Economics

...?First Fundamental Theorem of Welfare Economics The first fundamental theorem of welfare economics is simply a re ment of Adam Smith’s theory in economics. Adam Smith’s “invisible hand” theory postulates that in competitive markets, there is finally efficient allocation of resources and the first fundamental theory states that relates competitive equilibrium in the market and Pareto optimality. The theorem states that “If the local non-satiation condition for consumers is satisfied and [(x0i), (y0j), (Ф)] is a competitive equilibrium, then the allocation [(x0i), (y0j)] is Pareto optimal.” Before the proof is done, three conditions have to be defined, the first condition being that an allocation of resources is feasible, and the second...

### The Pythagorean Theorem

...THE PYTHAGOREAN THEOREM [Source: http www.arcytech.org/java/pythagoras/preface.html] April 30, 2008 The Pythagorean Theorem In mathematics, the Pythagorean Theorem is a relation in Euclidean geometry among the three sides of a right triangle. The theorem is named after the Greek mathematician Pythagoras who lived in the 6th century B.C. The theorem is as follows: "In any right angle triangle, the area of the square of the side opposite the right angle i.e. whose side is the hypotenuse is equal to the sum of the areas of the squares of the two sides that meet at a right angle i.e. whose sides are the two legs" In other words The square on the hypotenuse is equal to the sum of the squares on the other two sides Geometric...

### Pythagorean Theorem

...Pythagorean Theorem (Add (Add (Add Pythagorean Theorem Introduction Evidences show that Pythagorean Theorem was popular even among ancient civilizations. This famous theorem was developed by the Greek mathematician and philosopher Pythagoras. Historical writings argue that though Babylonian mathematicians had knowledge in the theorem, they could not develop it into a mathematical framework. Unlike any other mathematical theorem, the Pythagorean Theorem is supported by both geometric and algebraic proofs. This paper will discuss the Pythagorean Theorem in detail...

### 5-color theorem

... Five-Color Theorem The five color theorem, also referred to as the five color map theorem, is a mathematical theoremthat was developed from the graph theory. The theorem states that for a given plane divided into adjoining regions, such that it results in a form of a map of countries, no more than five colors are necessary to color the regions of the political map such that no two neighboring areas of the map are colored with the similar color. The five color theorem was developed as an extension to the four color theorem which was proved to have an error in its proof. To understand the five color theory it is necessary to go to the history behind the development of the color theorems. There are three of them, four-color, five-color...

### Divorce and the Coase Theorem

Divorce is a lawful procedure in which an adjudicator or any other power dissolves the bonds of marriage offered between two people, hence restoring them to the position of being on there own and permitting them to wed other persons. Most states in America have their own laws when it comes to divorce. Most of them allow no-fault divorce. This is where termination of matrimony does not need an assertion or evidence of mistake of whichever party. . With introduction of no-faulty divorce, it motivated a countrywide discussion over dissociate change. Followers of no-fault divorce renowned that there were various troubles with alternative arrangement divorce
I would not advocate for a change in the current law. This is for the ratio...

### Coase Theorem

...Coase Theorem Coase Theorem Coase theorem targets economic efficiency that is attributed to economic allocation and outcome when externalities are present. The theory stipulates that if trade is possible in the presence of an externality when transaction costs are significantly low, the end result will be an efficient outcome when initial allocation of property is not considered. The major obstacles to Coasian bargaining emerge when property rights have been defined poorly (Buchanan, 2005). This paper will discuss Coase theorem as an alternative to government regulation in terms of facilitating for the provision of goods and services. Ronald Coase stipulated that transaction costs that are found in the real world are not sufficiently low...

### Applying the Pythagorean Theorem

...﻿Applying the Pythagorean Theorem The Pythagorean Theorem is used to determine the areal distance of a right angled road trip. Through determining the length of each road and applying the Pythagorean formula [c= √(a2+b2)], the areal distance is determined (Kramer, 2011). Pythagorean Theorem is highly effective and easy to use as compared to the other mathematical tools. For measuring the length of each road, the odometer tool of car or other motor are used. For determining the distance, no other geometrical tool is required. Moreover, for resolving such kind of issues Global Positioning System (GPS) navigation is used in the modern day. This GPS navigation also requires the application of Pythagorean Theorem (Maor, 2007). Pythagorean...
