test3: Approximate Poisson generator

Description

This function considers the possible values of a Poisson random variable to lay within 3*sqrt(lambda) of lambda and is proposed for comparison with the regular rpois generator.

Usage

test3(Nsim = 10^4, lambda = 100)

Arguments

Nsim

Number of simulations

lambda

Poisson parameter

Value

This function produces a integer vector of size Nsim

warning

The output is not an exact Poisson sample because of the truncation on the support. Use rpois instead.

Details

This function replicates rpois(Nsim,lambda) and thus should not be used.
