Gamma distribution point percent function (PPF).Unit
Probabilities
Declaration
Function GammaCDFInv(p, a, b: TSample): TSample;
Result
the Gamma distribution point percent function (PPF) for probability y using the parameters a and b. Both parameters a and b must be positive, otherwise the result is NAN. If p does not lie on the interval [0,1], the result is NAN. The inverse gamma cumulative distribution function is defined by the following equation:
where G is the Gamma function.

Declaration
Procedure GammaCDFInv(P: TDenseMtxVec; A, B: TSample; Res: TDenseMtxVec);
Description
Calculates the inverse Gamma CDF for probability vector P using the parameters A and B. The results are stored in vector Res. The Res Length and Complex properties are adjusted automatically. If vector X is complex, an exception is raised.| Copyright 2008 Dew Research |
