Probabilities.ParetoCDFInv Method

Overload List

#SignatureDescription
1void ParetoCDFInv(TDenseMtxVec P, Double a, Double b, TDenseMtxVec Res)Pareto distribution PPF (vectorized).
2Double ParetoCDFInv(Double p, Double a, Double b)Pareto distribution point percent function (PPF).

Overload 1: void ParetoCDFInv(TDenseMtxVec P, Double a, Double b, TDenseMtxVec Res)

Pareto distribution PPF (vectorized).

#NameDescription
1PDefines distribution probabilities, real vector or matrix with values within closed interval [0,1].
2aDistribution scale parameter, real positive value.
3bDistribution shape parameter, real positive value, smaller than x.
4ResAfter calculation stores the PPF calculated from P, a and b. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of P.

Result: stored in self (calling object)

Overload 2: Double ParetoCDFInv(Double p, Double a, Double b)

Pareto distribution point percent function (PPF).

#NameDescription
1pProbability, real value on closed interval [0,1].
2aDistribution shape parameter, real positive value.
3bDistribution scale parameter (lower bound of the support), real positive value.

Returns: Double - the Pareto distribution point percent function (PPF) for probability p using the parameters a and b. p must lie in [0,1], otherwise the result is NAN; at p = 1 the result is +INF.

Remarks:

The inverse Pareto cumulative distribution function (quantile) is

CDF^(-1)(p| a,b)=b (1-p)^(-1/a), 0 <= p lt; 1

It is the solution x of CDF(x | a,b) = p. Domain: probability p in [0,1], a > 0, b > 0. At p = 1 the result is +INF. For p < 0 or p > 1 the result is NAN.
