cumulativeProbability(double x0, double x1) For a random variable X whose values are distributed according
to this distribution, this method returns P(x0 ≤ X ≤ x1).
public double cumulativeProbability(double x0, double x1) throws MathException(Code)
For a random variable X whose values are distributed according
to this distribution, this method returns P(x0 ≤ X ≤ x1).
The default implementation uses the identity
P(x0 ≤ X ≤ x1) = P(X ≤ x1) - P(X ≤ x0)
Parameters: x0 - the (inclusive) lower bound Parameters: x1 - the (inclusive) upper bound the probability that a random variable with this distributionwill take a value between x0 and x1,including the endpoints. throws: MathException - if the cumulative probability can not becomputed due to convergence or other numerical errors. throws: IllegalArgumentException - if x0 > x1
