Overdispersed Meaning In Urdu with Detail
In probability theory and statistics, the Dirichlet-multinomial distribution is a family of discrete multivariate probability distributions on a finite support of non-negative integers. It is also called the Dirichlet compound multinomial distribution (DCM) or multivariate Pólya distribution (after George Pólya). It is a compound probability distribution, where a probability vector p is drawn from a Dirichlet distribution with parameter vector , and an observation drawn from a multinomial distribution with probability vector p and number of trials n. The compounding corresponds to a Pólya urn scheme. It is frequently encountered in Bayesian statistics, empirical Bayes methods and classical statistics as an overdispersed multinomial distribution.
