Generate Random Variables from a Multinomial Sampling Model

Description

Generates a random vector from a binomial sampling model.

Usage

  rvmultinom(n=1, size=1, prob)

Arguments

n integer, number of random variables to generate
size integer or integer-valued rv: the number of trials (size of each sample)
prob vector (of length at least 3) prior probabilities of successes of each trial (may be constant or an rv object)

Details

The vector prob will be normalized to have sum 1.

If length(prob) is two, rvbinom is called instead.

Value

A random vector of length length(prob)*n.
