public class RandGenPoisson : RandomNumberGenerator

The RandGenPoisson type exposes the following members.

Constructors
  NameDescription
Public methodRandGenPoisson
Constructs a random number generator using a RandGenMTwist as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with mean equals 1.
Public methodRandGenPoisson(Double)
Constructs a random number generator using a RandGenMTwist as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with the specified mean.
Public methodRandGenPoisson(Int32)
Constructs a random number generator using a seeded RandGenMTwist as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with mean equals 1.
Public methodRandGenPoisson(RandomNumberGeneratorUniformRandomNumber)
Constructs a random number generator using the given delegate as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with mean equals 1.
Public methodRandGenPoisson(Double, RandomNumberGeneratorUniformRandomNumber)
Constructs a random number generator using the given delegate as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with the specified mean.
Public methodRandGenPoisson(Double, Int32)
Constructs a random number generator using a seeded RandGenMTwist as the underlying uniform random number generator. The generated deviates will follow a Poisson distribution with the specified mean.

Remarks
A random variable is said to have a Poisson distribution if it as a probability density function f(x) = (m**x)*exp(-m)/x!. The mean and variance of a Poisson distribution is m.
