| Method Summary | |
| double | cumulativeProbability(double x)
For a random variable X whose values are distributed according
to this distribution, this method returns P(X ≤ x). | | double | 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). |
| cumulativeProbability | | double cumulativeProbability(double x) throws MathException(Code) | | For a random variable X whose values are distributed according
to this distribution, this method returns P(X ≤ x). In other words,
this method represents the (cumulative) distribution function, or
CDF, for this distribution.
Parameters:
x - the value at which the distribution function is evaluated. the probability that a random variable with thisdistribution takes a value less than or equal to x
throws:
MathException - if the cumulative probability can not becomputed due to convergence or other numerical errors. |
| cumulativeProbability | | 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).
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 |
