(Overrides ProbabilityDistributionInverseCDF(Double).)
Protected methodInverseCdfUsingBracket
Uses a bracketing method to evaluate the inverse of cumulative distribution functions.
(Inherited from ProbabilityDistribution.)
Protected methodInverseDiscreteCdfUsingBracket

Remarks
The chi-square distribution is a special case of the gamma distribution with alpha = df/2 and beta = 2, where df is the degrees of freedom.
