Properties of multinomial distribution
WebIt is a multivariate generalization of the beta distribution, hence its alternative name of multivariate beta distribution (MBD). Dirichlet distributions are commonly used as prior distributions in Bayesian statistics, and in fact, the Dirichlet distribution is the conjugate prior of the categorical distribution and multinomial distribution.

Web— The multinomial distribution is the number of different outcomes from multiple categorical events … It is a generalization of the binomial distribution to more than two … The binomial distribution generalizes this to the number of heads from performing n independent flips (Bernoulli trials) of the same coin. The multinomial distribution models the outcome of n experiments, where the outcome of each trial has a categorical distribution, such as rolling a k -sided die n times. See more In probability theory, the multinomial distribution is a generalization of the binomial distribution. For example, it models the probability of counts for each side of a k-sided dice rolled n times. For n independent trials … See more In some fields such as natural language processing, categorical and multinomial distributions are synonymous and it is common to speak of a multinomial distribution when a See more First, reorder the parameters $${\displaystyle p_{1},\ldots ,p_{k}}$$ such that they are sorted in descending order (this is only to speed up computation and not strictly necessary). Now, for each trial, draw an auxiliary variable X from a uniform (0, 1) distribution. … See more Probability mass function Suppose one does an experiment of extracting n balls of k different colors from a bag, replacing the extracted balls after each draw. Balls of … See more Expected value and variance The expected number of times the outcome i was observed over n trials is $${\displaystyle \operatorname {E} (X_{i})=np_{i}.\,}$$ See more Equivalence tests for multinomial distributions The goal of equivalence testing is to establish the agreement between a theoretical … See more
