Weibull cumulative distribution function (CDF).

Syntax
C#
Visual Basic
public static double WeibullCDF(double x, double a, double b);
Parameters
Parameters 
Description 
double x 
Function domain, zero or real positive value. 
double a 
Distribution scale parameter, real positive value. 
double b 
Distribution shape parameter, real positive value. 
Returns

the Weibull cumulative distribution function for value x using the parameters a and b. Value x must be greater or equal than zero and parameters a and b must be positive numbers, otherwise the result is NAN.

Remarks

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

 

where I is the interval on which the Weibull CDF is not zero.
