C# Класс NSoft.NFramework.Numerics.Distributions.Continuous.Chi

This class implements functionality for the Chi distribution.
This distribution is a continuous probability distribution.
The distribution usually arises when a k-dimensional vector's orthogonal components are independent and each follow a standard normal distribution. The length of the vector will then have a chi distribution.
Wikipedia - Chi 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.
