The GammaDistribution type exposes the following members.

Constructors

	Name	Description
	GammaDistribution	Default constructor. Constructs a GammaDistribution instance with alpha and beta equal to 1.
	GammaDistribution(Double, Double)	Constructs a GammaDistribution instance with the given alpha and beta.

Properties

	Name	Description
	Alpha	Gets and sets the alpha shape parameter.
	Beta	Gets and sets the beta shape parameter.
	Kurtosis	Gets the kurtosis, a measure of the degree of peakednesss of the distribution.
	Mean	Gets the mean of the distribution.
	Skewness	Gets the skewness, a measure of the degree of asymmetry of this distribution.
	Variance	Gets the variance of the distribution.

Methods

	Name	Description
	CDF	Returns the cumulative density function evaluated at a given value. (Overrides ProbabilityDistributionCDF(Double).)
	Clone	Creates a deep copy of this GammaDistribution. (Overrides ProbabilityDistributionClone.)
	InverseCDF	Returns the inverse cumulative density function evaluated at a given value. (Overrides ProbabilityDistributionInverseCDF(Double).)
	InverseCdfUsingBracket	Uses a bracketing method to evaluate the inverse of cumulative distribution functions. (Inherited from ProbabilityDistribution.)
	InverseDiscreteCdfUsingBracket	Uses a bracketing method to evaluate the inverse of cumulative distribution functions for discrete distributions. (Inherited from ProbabilityDistribution.)
	PDF	Returns the probability density function evaluated at a given value. (Overrides ProbabilityDistributionPDF(Double).)
	ToString	Returns a formatted string representation of this distribution. (Overrides ProbabilityDistributionToString.)

Remarks

The gamma distribution is a family of curves with two free parameters: alpha and beta. When alpha is large, the gamma distribution closely approximates a normal distribution.
