public class PascalGen
extends RandomVariateGenInt

Implements Pascal random variate generators, which is a special case of the negative binomial generator with parameter γ equal to a positive integer. See NegativeBinomialGen for a description.


Constructor Summary
PascalGen(RandomStream s, int n, double p)
          Creates a Pascal random variate generator with parameters n and p, using stream s.
PascalGen(RandomStream s, PascalDist dist)
          Creates a new generator for the distribution dist, using stream s.
 
Method Summary
 int getN()
          Returns the parameter n of this object.
 double getP()
          Returns the parameter p of this object.
static int nextInt(RandomStream s, int n, double p)
          Generates a new variate from the Pascal distribution, with parameters n = n and p = p, using stream s.
