weibullv

double weibullv(double p, double g, double b);

Returns the critical point of the Weibull random variable distribution function with gamma g and beta b associated with probability p.

Parameters:
pCummulative probability for the critical point.
gShape parameter.
bScale parameter.

Returns:
x such that P(X ≤ x | g, b) = p

Errors:
NUMERICS_ERROR is raised if g ≤ 0, b ≤ 0, p ≤ 0, or p ≥ 1

Usage:
double x = weibullv(.5, 1.5, 2.75)
