umontreal.iro.lecuyer.randvar.CauchyGen
public class CauchyGen
This class implements random variate generators for the Cauchy distribution. The density is
The (non-static) nextDouble method simply calls inverseF on the distribution.
| Constructor Summary | |
|---|---|
CauchyGen(RandomStream s)
Creates a Cauchy random variate generator with parameters α = 0 and β = 1, using stream s. |
|
CauchyGen(RandomStream s,
CauchyDist dist)
Create a new generator for the distribution dist, using stream s. |
|
CauchyGen(RandomStream s,
double alpha,
double beta)
Creates a Cauchy random variate generator with parameters α = alpha and β = beta, using stream s. |
|
| Method Summary | |
|---|---|
double |
getAlpha()
Returns the parameter α of this object. |
double |
getBeta()
Returns the parameter β of this object. |
static double |
nextDouble(RandomStream s,
double alpha,
double beta)
Generates a new variate from the Cauchy distribution with parameters α = alpha and β = beta, using stream s. |
