inv
Provides the inverse cumulative distribution function for the distribution
While closed form solutions for the inverse cdf may not exist, numerical search methods can be used to solve F(X) = p.
Return
The inverse cdf evaluated at the supplied probability
Parameters
p
The probability to be evaluated for the inverse, p must be 0,1 or an IllegalArgumentException is thrown
Computes x_p where P(X <= x_p) = p for the supplied array of probabilities. Requires that the values within the supplied array are in (0,1)
