 | Rand |
Class RandGenPoisson generates random numbers from an Poisson distribution.
Inheritance HierarchyNamespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
SyntaxThe RandGenPoisson type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RandGenPoisson | 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. |
| RandGenPoisson(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. |
| RandGenPoisson(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. |
| RandGenPoisson(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. |
| RandGenPoisson(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. |
| RandGenPoisson(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. |
Properties| Name | Description | |

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.
