Methods
  NameDescription
Public methodCDF
Returns the cumulative density function evaluated at a given value.
(Overrides ProbabilityDistributionCDF(Double).)
Public methodClone
Creates a deep copy of this GammaDistribution.
(Overrides ProbabilityDistributionClone.)
Public methodInverseCDF
Returns the inverse cumulative density function evaluated at a given value.
(Overrides ProbabilityDistributionInverseCDF(Double).)
Protected methodInverseCdfUsingBracket
Uses a bracketing method to evaluate the inverse of cumulative distribution functions.
(Inherited from ProbabilityDistribution.)
Protected methodInverseDiscreteCdfUsingBracket
Uses a bracketing method to evaluate the inverse of cumulative distribution functions for discrete distributions.

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.
