In miscF: Miscellaneous Functions

Description

Generate random samples from multinomial distributions with the same number of classes but different event probabilities.

Usage

   rMultinom(p)

Arguments

p	matrix with each row specifying the probabilities for different classes of each sample.

Details

This function vectorizes the generation of random samples from different multinomial distributions by the inversion of CDF method.

Value

Random samples from multinomial distributions.

Examples

  #Example 1: Generate 100 random samples from multinomial distributions
  #           with 3 classes and different event probabilities.
  p1 <- runif(100)
  p2  <- runif(100, 0, 1-p1)
  p3 <- 1-p1-p2 
  x <- rMultinom(p=cbind(p1, p2, p3))
