Summary
Cauchy distribution point percent function (PPF).
Unit
Probabilities
Declaration
Procedure CauchyCDFInv(P: TDenseMtxVec; m, b: TSample; Res: TDenseMtxVec);
Description
Calculates the inverse Cauchy CDF for probability vector P using the parameters b and m. 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 CauchyCDFInv(p, m, b: TSample): TSample;
Result
the Cauchy distribution point percent function (PPF) for given parameters b and m. Parameter b must be greater than zero and p must lie in the interval [0,1]. The inverse Cauchy cumulative distribution function is defined by the following equation:

The result of CauchyCDFInv is the solution of the integral equation of the Cauchy CDF with parameters b and m and with the desired probability p.
