Interface DiscreteDistribution

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

PoissonDistribution

public interface DiscreteDistribution
extends java.io.Serializable

This interface must be implemented by all the package's classes implementing a discrete random distribution. Distributions are not mutable.

Method Summary

int	generate() Generates a pseudo-random number.
double	probability(int n) Returns the probability of a given number.

Method Detail

generate

int generate()

Generates a pseudo-random number. The numbers generated by this function are drawn according to the pseudo-random distribution described by the object that implements it.

Returns:

A pseudo-random number.

probability

double probability(int n)

Returns the probability of a given number.

Parameters:

n - An integer.
