Weibull distribution point percent function (PPF).
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.
