ErlangCDFInv Routines
Summary
Erlang distribution point percent function (PPF).

Unit
Probabilities

Declaration
Procedure ErlangCDFInv(P: TDenseMtxVec; k: Integer; lambda: TSample; Res: TDenseMtxVec);

Description
Calculates the inverse Erlang CDF for probability vector P using the parameters k and lambda. 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.
Declaration
Function ErlangCDFInv(p: TSample; k: Integer; lambda: TSample): TSample;
Result
the Erlang distribution point percent function (PPF). Both parameters k and lambda must be positive, otherwise the result is NAN. The inverse of the Erlang cumulative distribution function is defined by the following equation:
