Public Methods

Method	Description
IsValidAlpha ( double value ) : bool	Determines whether the specified value is valid for parameter Alpha.
IsValidLambda ( double value ) : bool	Determines whether the specified value is valid for parameter Lambda.
NextDouble ( ) : double	Returns a weibull distributed floating point random number.
WeibullDistribution ( ) : System	Initializes a new instance of the WeibullDistribution class, using a StandardGenerator as underlying random number generator.
WeibullDistribution ( Generator generator ) : System	Initializes a new instance of the WeibullDistribution class, using the specified Generator as underlying random number generator.

Method	Description
Gamma ( double x ) : double	Represents a Lanczos approximation of the Gamma function.
UpdateHelpers ( ) : void	Updates the helper variables that store intermediate results for generation of weibull distributed random numbers.
