Method Detail

inverseCumulativeProbability

public double inverseCumulativeProbability(double p)
                                    throws MathException

For this disbution, X, this method returns x such that P(X < x) = p.

Parameters:

p - the cumulative probability.

Returns:

x.

Throws:

MathException - if the inverse cumulative probability can not be computed due to convergence or other numerical errors.
