An Introduction to the Multinomial Distribution - Statology

WebAn example where a multinomial random variable could occur is during the throw of a dice. Let Xi, i = 1, 2, … , 6, denote the number of times i is observed in n throws of a dice. Then X = ( X1, X2, … , X6) has a multinomial distribution. If the dice is fair, then for all i. The PMF of the multinomial distribution is given by where .

"WebThe multinomial distribution is a multivariate generalization of the binomial distribution. Take an experiment with one of p possible outcomes. An example of such an experiment is throwing a dice, where the outcome can be 1 through 6. Each sample drawn from the distribution represents n such experiments.
