umontreal.iro.lecuyer.randvar.HypergeometricGen
public class HypergeometricGen
This class implements random variate generators for the hypergeometric distribution. Its mass function is
The generation method is inversion using the chop-down algorithm
| Constructor Summary | |
|---|---|
HypergeometricGen(RandomStream s,
HypergeometricDist dist)
Creates a new generator for distribution dist, using stream s. |
|
HypergeometricGen(RandomStream s,
int m,
int l,
int k)
Creates a hypergeometric generator with parameters m = m, l = l and k = k, using stream s. |
|
