Probabilities.TriangularCDFInv Function

Triangular distribution point percent function (PPF).

Pascal

function TriangularCDFInv(p: double; a: double; b: double; c: double): double; overload;

Parameters	Description
p	Probability, real positive value on closed interval [0,1].
a	Distribution locagtion parameter, real value, smaller than parameter b.
b	Distribution scale parameter, real value, greater than parameter a.
c	Distribution shape parameter, real value on closed interval [a,b].

Returns

the Triangular distribution point percent function (PPF) for probability y using distribution parameters a,b,c.

Description

function TriangularCDF(x: single; a,b,c: single): single; overload;

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

The result of TriangularCDFInv is the solution of the integral equation of the TriangularCDF with parameters a,b,c where you must specify the probability p.
