All Implemented Interfaces:

java.io.Serializable

public class GVrandom
extends java.util.Random

Extends the functionality of java.util.Random by providing a method to generate the next random value in a Poisson process. One characteristic of the Poisson distribution is that the mean of many generated values equals the variance.
