C# Class NSoft.NFramework.Numerics.Distributions.Continuous.ChiSquare

This class implements functionality for the ChiSquare distribution.
This distribution is a sum of the squares of k independent standard normal random variables.
Wikipedia - ChiSquare distribution.

The distribution will use the System.Random by default. Users can set the random number generator by using the RandomSource property.

The statistics classes will check all the incoming parameters whether they are in the allowed range. This might involve heavy computation. Optionally, by setting Control.CheckDistributionParameters to false, all parameter checks can be turned off.
