Public Methods

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

Method	Description
UpdateHelpers ( ) : void	Updates the helper variables that store intermediate results for generation of gamma distributed random numbers.
