Probabilities.TriangularCDF Method (double, double, double, double)

Triangular cumulative distribution function (CDF).

Syntax
C#
Visual Basic
public static double TriangularCDF(double x, double a, double b, double c);
Parameters 
Description 
double x 
Distribution domain, real value on closed interval [a,b]. 
double a 
Distribution locagtion parameter, real value, smaller than parameter b. 
double b 
Distribution scale parameter, real value, greater than parameter a. 
double c 
Distribution shape parameter, real value on closed interval [a,b]. 

the triangular cumulative distribution function for value x using the parameters a,b,c.

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].
