## Base rate information theory

BASE-RATE FALLACY: "If you overlook the base-rate information that 90% and then 10% of a population consist of lawyers and engineers, respectively, you would form the base-rate fallacy that someone who enjoys physics in school would probably be categorized as an engineer rather than a lawyer. Information & Entropy •Information Equation p = probability of the event happening b = base (base 2 is mostly used in information theory) *unit of information is determined by base base 2 = bits base 3 = trits base 10 = Hartleys base e = nats concepts of information are grounded in the principles and rules of probability. Entropies Deﬁned, and Why They Are Measures of Information. Marginal entropy, joint entropy, conditional entropy, and the Chain Rule for entropy. Mutual information between ensembles of random variables. Why entropy is a fundamental measure of information content. such as entropy rate and information rate. When considering multiple random objects, in addition to information we will be concerned with the distance or distortion between the random objects, that is, the accuracy of the representa- Information theory, the mathematical theory of communication, has two primary goals: The rst is the Rate Case Training 5 25 Rate Base Components Plant in service Largest component of a company’s rate base Generally, one of the least controversial aspects of a rate proceeding unless the prudence of construction is an issue or excess capacity is at issue

## Sep 24, 2019 Reality, however, tends to contradict this theory. Often, market participants overreact to new information, such as a change in interest rates,

However, base rate fallacy occurs because people tend to ignore all of this relevant base rate information and instead rely on mental shortcuts, such as the idea that a car accident occurs when we In probability and statistics, base rate generally refers to the (base) class probabilities unconditioned on featural evidence, frequently also known as prior probabilities. Base on modern portfolio theory, a model is developed on the purpose of telling the real price of a stock. This model helps investors to make the decision of buying a stock easier because they know that the price of the stock that they are going to invest is higher or lower A base rate is a phenomenon’s basic rate of incidence. The base rate fallacy describes how people do not take the base rate of an event into account when solving probability problems.

Often, market participants overreact to new information, such as a change in interest rates, However, base rate fallacy occurs because people tend to ignore all of this relevant base rate information and instead rely on mental shortcuts, such as the idea The base-rate fallacy is people's tendency to ignore base rates in favor of, e.g., I. AjzenIntuitive theories of events and the effects of base-rate information on Base Rate Fallacy is our tendency to give more weight to the event-specific information than we should, and sometimes even ignore base rates entirely. Describes and gives examples of the formal base rate statistical fallacy. use Bayes' Theorem from probability theory: Let "h" represent the proposition that Pat

The base rate fallacy describes how people do not take the base rate of an event into account when solving probability problems. The information entropy, often just entropy, is a basic quantity in information theory associated to any random variable, which can be interpreted as the average level of "information", "surprise", or "uncertainty" inherent in the variable's possible outcomes.The concept of information entropy was introduced by Claude Shannon in his 1948 paper "A Mathematical Theory of Communication".

The basic idea of information theory is to measure the rate of information flow as is conventional to take the log in the formula to base 2, so that the entropy of a. probability theory. Examples of such “errors” include overconfidence bias, con- junction fallacy, and base-rate neglect. Researchers have relied on a very narrow .
