In probability and statistics, a mixture distribution is the probability distribution of a random variable that is derived from a collection of other random variables as follows: first, a random variable is selected by chance from the collection according to given probabilities of selection, and then the value of the … Meer weergeven Given a finite set of probability density functions p1(x), ..., pn(x), or corresponding cumulative distribution functions P1(x), ..., Pn(x) and weights w1, ..., wn such that wi ≥ 0 and Σwi = 1, the mixture distribution can be … Meer weergeven The mixture components are often not arbitrary probability distributions, but instead are members of a parametric family (such as normal distributions), with different … Meer weergeven Two normal distributions Simple examples can be given by a mixture of two normal distributions. (See Multimodal distribution#Mixture of two normal distributions Meer weergeven • Compound distribution • Contaminated normal distribution • Convex combination • Expectation-maximization (EM) algorithm Meer weergeven Where the set of component distributions is uncountable, the result is often called a compound probability distribution. The construction of such distributions has a formal similarity to that of mixture distributions, with either infinite summations … Meer weergeven Convexity A general linear combination of probability density functions is not necessarily a probability density, since it may be negative or it may integrate to something other than 1. However, a convex combination of … Meer weergeven Mixture densities are complicated densities expressible in terms of simpler densities (the mixture components), and are used both because they provide a good model … Meer weergeven WebA distribution channel is a network of distributors or intermediaries that ensures the delivery of products from manufacturers to end-users.
