umontreal.iro.lecuyer.randvar.ChiGen
public class ChiGen
This class implements random variate generators for the chi distribution. It has ν > 0 degrees of freedom and its density function is
GammaGen.
The (non-static) nextDouble method simply calls inverseF on the distribution (slow).
| Constructor Summary | |
|---|---|
ChiGen(RandomStream s,
ChiDist dist)
Create a new generator for the distribution dist, using stream s. |
|
ChiGen(RandomStream s,
int nu)
Creates a chi random variate generator with ν = nu degrees of freedom, using stream s. |
|
| Method Summary | |
|---|---|
int |
getNu()
Returns the value of ν for this object. |
static double |
nextDouble(RandomStream s,
int nu)
Generates a random variate from the chi distribution with ν = nu degrees of freedom, using stream s. |
