Multinomial Distribution
The multinomial distribution models the probability of each combination of successes in a series of independent trials.
Multinomial Probability Distribution Objects
This example shows how to generate random numbers, compute and plot the pdf, and compute descriptive statistics of a multinomial distribution using probability distribution objects.
Multinomial Probability Distribution Functions
This example shows how to generate random numbers and compute and plot the pdf of a multinomial distribution using probability distribution functions.
