umontreal.iro.lecuyer.randvar.PoissonGen
public class PoissonGen
This class implements random variate generators having the Poisson distribution. Its mass function is
No local copy of the parameter λ = lambda is maintained in this class. The (non-static) nextInt method simply calls inverseF on the distribution.
| Constructor Summary | |
|---|---|
PoissonGen(RandomStream s,
double lambda)
Creates a Poisson random variate generator with parameter λ = lambda, using stream s. |
|
PoissonGen(RandomStream s,
PoissonDist dist)
Creates a new random variate generator using the Poisson distribution dist and stream s. |
|
| Method Summary | |
|---|---|
double |
getLambda()
Returns the λ associated with this object. |
static int |
nextInt(RandomStream s,
double lambda)
A static method for generating a random variate from a Poisson distribution with parameter λ = lambda. |
