C# 클래스 NSoft.NFramework.Numerics.Distributions.Discrete.ConwayMaxwellPoisson

The Conway-Maxwell-Poisson distribution is a generalization of the Poisson, Geometric and Bernoulli distributions. It is parameterized by two real numbers "lambda" and "nu". For nu = 0 the distribution reverts to a Geometric distribution nu = 1 the distribution reverts to the Poisson distribution nu -> infinity the distribution converges to a Bernoulli distribution

This implementation will cache the value of the normalization constant. Wikipedia - ConwayMaxwellPoisson 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.
