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

The inverse Gamma distribution is a distribution over the positive real numbers parameterized by two positive parameters. Wikipedia - InverseGamma 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.
