umontreal.iro.lecuyer.randvar.NegativeBinomialGen
public class NegativeBinomialGen
This class implements random variate generators having the negative binomial distribution. Its mass function is
No local copy of the parameters n and p is maintained in this class. The (non-static) nextInt method simply calls inverseF on the distribution.
