Chapter 4 Multivariate distributions
RS – 4 – Multivariate Distributions 3 Example: The Multinomial distribution Suppose that we observe an experiment that has k possible outcomes {O1, O2, …, Ok} independently n times.Let p1, p2, …, pk denote probabilities of O1, O2, …, Ok respectively. Let Xi denote the number of times that outcome Oi occurs in the n repetitions of the experiment.

Because the way in which these vectors of measurements turn out is governed by probability, we need to discuss extensions of usual univari-
