Parameters
Parameters 
Description 
x 
Distribution domain, real value on closed interval [a,b]. 
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 cumulative distribution function for value x using the parameters a,b,c.

Description

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

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

 

The result of TriangularCDF is the probability that a single observation from the triangular distribution with location parameter a, scale parameter b and shape parameter c fall in the interval (a,x].
