test1: Poor chi-square generator

In mcsm: Functions for Monte Carlo Methods with R

Description

This function is a direct implementation of the transform principle for the chi-square distribution, with poor performances even though the output is correct.

Usage

test1(Nsim = 10^4, df = 6)

Arguments

Nsim	Number of simulations
df	Degrees of freedom

Details

This function replicates rchisq(Nsim,df) and thus should not be used.

Value

This function produces a numerical vector of size Nsim.

warning

For efficient chi-square simulation, make sure to use rchisq
