Probabilities.PowerCDFInv Function

Power distribution point percent function (PPF).

Pascal

function PowerCDFInv(p: double; alpha: double; beta: double): double; overload;

Parameters	Description
p	Probability, real positive value on closed interval [0,1].
alpha	Distribution shape parameter, real positive value..
beta	Distribution scale parameter, positive real number.

Returns

the Power distribution point percent function (PPF) for probability p using the parameters alpha and beta. Probability p must lie on the interval [0,1], and alpha, beta must be positive scalars, otherwise the result is NAN.

Description

The inverse Pareto cumulative distribution function is defined by the following equation:
