public interface Distribution
Base interface for probability distributions.
| Method Summary | |

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). |

double cumulativeProbability(double x)
throws MathException
x - the value at which the distribution function is evaluated.
x
MathException - if the cumulative probability can not be
computed due to convergence or other numerical errors.
double cumulativeProbability(double x0,
double x1)
throws MathException
x0 - the (inclusive) lower boundx1 - the (inclusive) upper bound
x0 and x1,
including the endpoints
MathException - if the cumulative probability can not be
computed due to convergence or other numerical errors.
IllegalArgumentException - if x0 > x1
