Probabilities.PowerPDF Function

Power probability distribution function (PDF).

Pascal

function PowerPDF(x: double; alpha: double; beta: double): double; overload;

Parameters	Description
x	Function domain, real on closed interval [0,1/beta]
alpha	Distribution shape parameter, real positive value..
beta	Distribution scale parameter, positive real number.

Returns

Power distribution PDF, evaluated at x using parameters alpha and beta. Alpha, beta parameters must be positive and 0 <= x <= 1/beta, otherwise the result is NAN.

Description

Power probability distribution function is defined by the following equation:

where alpha, beta are both positive scalars and 0 <= x <= 1/beta.
