Probabilities.WeibullCDFInv Method (double, double, double)

Weibull distribution point percent function (PPF).

Syntax
C#
Visual Basic
public static double WeibullCDFInv(double p, double a, double b);
Parameters 
Description 
double p 
Probability, real positive value on closed interval [0,1]. 
double a 
Distribution scale parameter, real positive value. 
double b 
Distribution shape parameter, real positive value. 

the Weibull distribution point percent function (PPF) for probability p using the parameters a and b. Probability p must lie on the interval [0,1] and parameters a and b must be positive numbers, otherwise the result is NAN.

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

 

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