          Create a new generator for the distribution dist, using stream s.
ChiRatioOfUniformsGen(RandomStream s, int nu)
          Creates a chi random variate generator with ν = nu degrees of freedom, using stream s.
 
Method Summary
 double nextDouble()
          Generates a random number from the continuous distribution contained in this object.

Constructor Detail

ChiRatioOfUniformsGen

public ChiRatioOfUniformsGen(RandomStream s,
                             int nu)
Creates a chi random variate generator with ν = nu degrees of freedom, using stream s.


ChiRatioOfUniformsGen

public ChiRatioOfUniformsGen(RandomStream s,
                             ChiDist dist)
Create a new generator for the distribution dist, using stream s.

Method Detail

nextDouble

public double nextDouble()
Description copied from class: RandomVariateGen
Generates a random number from the continuous distribution contained in this object. By default, this method uses inversion by calling the inverseF method of the distribution object. Alternative generating methods are provided in subclasses.

Overrides:
nextDouble in class RandomVariateGen
Returns:
the generated value

nextDouble

public static double nextDouble(RandomStream s,
                                int nu)
