What is entropy in statistics

Information entropy is the average rate at which information is produced by a stochastic source or uncertainty, and the definition of entropy used in information theory is directly analogous to the definition used in statistical thermodynamics. A Statistical Definition of Entropy. The list of the $ p_i$ is a precise description of the randomness in the system, but the number of quantum states in almost. The entropy tells you how much uncertainty is in the system. Let's say you're looking for a cat, and you know that it's somewhere between your.

Most of the material on this page has been moved to a new page on information theory models. The terms entropy, uncertainty, and information are used more or . the entropy I is defined as a measure of uncertainty of the probability distribution nonextensive statistics[6][7][8] (NES) proposed to use some entropies for. Equation 6 below is the general form of the definition of entropy in statistical mechanics, as first.
