draw.multivariate.hypergeometric: Pseudo-Random Number Generation under Multivariate...

In MultiRNG: Multivariate Pseudo-Random Number Generation

Description

This function implements pseudo-random number generation for a multivariate hypergeometric distribution.

Usage

draw.multivariate.hypergeometric(no.row,d,mean.vec,k)

Arguments

no.row	Number of rows to generate.
d	Number of variables to generate.
mean.vec	Number of items in each category.
k	Number of items to be sampled. Must be a positive integer.

Value

A no.row \times d matrix of generated data.

Examples

meanvec=c(10,10,12) ; myk=5
mydata=draw.multivariate.hypergeometric(no.row=1e5,d=3,mean.vec=meanvec,k=myk)
apply(mydata,2,mean)-myk*meanvec/sum(meanvec)
