Multinomial probability distribution examples
Web6 nov. 2024 · This is a good example of a multinomial probability distribution with 30 categories, and since the number of samples are large it will approximate a binomial distribution. Thus, we can apply binomial probability distributions for calculating the probabilities in our multinomial data. 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.
