C# Class YAMP.Numerics.PoissonDistribution

Provides generation of poisson distributed random numbers.

The poisson distribution generates only discrete numbers.
The implementation of the PoissonDistribution type bases upon information presented on Wikipedia - Poisson distribution and the implementation in the Communication Networks Class Library.

Inheritance: Distribution
