Random data generation for the zero-infalted Poisson distribution with Poisson parameter lambda and zero proportion prop.zero.

Given the number of samples desired, a Poisson parameter, lambda, and a zero proportion, prop.zero, simulates the number of desired samples from ZIP(lambda, prop.zero).

Usage

rzipoisson(n, lambda, prop.zero)

Arguments

n

The number of samples to be simulated.

lambda

The Poisson rate parameter.

prop.zero

The proportion of excess zeroes.

Value

Simulated data from ZIP(lambda, prop.zero).
