test3: Approximate Poisson generator

Description Usage Arguments Details Value warning Author(s) References See Also Examples

View source: R/test3.R

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

1
test3(Nsim = 10^4, lambda = 100)

Arguments

Nsim

Number of simulations

lambda

Poisson parameter

Details

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

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.
