public class PascalConvolutionGen
extends PascalGen

Implements Pascal random variate generators by the convolution method. The method generates n geometric variates with probability p and adds them up.

The algorithm is slow if n is large.


Constructor Summary
PascalConvolutionGen(RandomStream s, int n, double p)
          Creates a Pascal random variate generator with parameters n and p, using stream s.
PascalConvolutionGen(RandomStream s, PascalDist dist)
          Creates a new generator for the distribution dist, using stream s.
