public class COptQuestChiSquareRandomVariable
extends COptQuestUserControlledVariable

A random variable with a chi-squared distribution: the sum of the squares of df independent standard normal values. df, the degrees of freedom, is a positive integer. The mean is df.

The engine draws a new value at the start of every replication. The probability distribution is COptQuestChiSquareDistribution.
