public class NormalACRGen
extends NormalGen

This class implements normal random variate generators using the acceptance-complement ratio method. For all the methods, the code was taken from UNURAN.

A local copy of the parameters μ and σ is maintained in this class.

Constructor Detail

NormalACRGen

public NormalACRGen(RandomStream s,
                    NormalDist dist)
Creates a random variate generator for the normal distribution dist and 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 NormalGen
Returns:
the generated value

nextDouble

public static double nextDouble(RandomStream s,
                                double mu,
                                double sigma)
