THE MULTINOMIAL DISTRIBUTION AND ELEMENTARY TESTS FOR CATEGORICAL DATA

THE MULTINOMIAL DISTRIBUTION AND ELEMENTARY TESTS FOR CATEGORICAL DATA. It is useful to have a probability model for the number of observations falling into each of k mutually exclusive classes. Such a model is given by the multinomial random variable , for which it is assumed that :
