Constructors
  NameDescription
Public methodRandGenBeta
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with alpha and beta equal to one.
Public methodRandGenBeta(Double)
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha. The beta parameter defaults to one.
Public methodRandGenBeta(Int32)
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with alpha and beta equal to one.
Public methodRandGenBeta(RandomNumberGeneratorUniformRandomNumber)
Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with alpha and beta equal to one.
Public methodRandGenBeta(Double, RandomNumberGeneratorUniformRandomNumber)
Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha. The beta parameter defaults to 1.
Public methodRandGenBeta(Double, Double)
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha and beta parameters.
Public methodRandGenBeta(Double, Int32)
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha. The beta parameter defaults to one.
Public methodRandGenBeta(Double, Double, RandomNumberGeneratorUniformRandomNumber)
Constructs a random number generator using the given delegate as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha and beta parameter.
Public methodRandGenBeta(Double, Double, Int32)
Constructs a random number generator using class RandGenMTwist as the underlying uniform random number generator. Generated random numbers will follow a beta distribution with the specified alpha and beta parameters.

Remarks
A random variable, W, is said to have a beta distribution of alpha a and beta b if it has a probability density function f(x) = (1 / beta(a, b)) * (x ^ (a - 1)) * ((1 - x) ^ (beta - 1)) where is the beta function.
