Constructors

	Name	Description
	RandGenBeta	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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
	RandGenBeta(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.
