Class NormalRandomVariable

    • Constructor Detail

      • NormalRandomVariable

        public NormalRandomVariable()
        Default constructor. Mean is set to zero and standard deviation is set to one.
      • NormalRandomVariable

        public NormalRandomVariable(double m,                    double s)
        Create a random variable with the given mean and standard deviation.
        Parameters:
        m - the mean.
        s - the standard deviation.
      • NormalRandomVariable

        public NormalRandomVariable(double m,                    double s,                    RNG source)
        Create a random variable with the given parameters.
        Parameters:
        m - the mean.
        s - the standard deviation.
        source - the source generator.
    • Method Detail

      • nextRandomVariable

        public static double nextRandomVariable(double m,                        double s,                        RNG source)

        Access the next random variable using the given generator.

        The implementation of this method is based on the Normal generator of Marsaglia and Bray.

        Parameters:
        m - the mean.
        s - the standard deviation.
        source - the source generator.
        Returns:
        the next random variable.
      • nextRandomVariable

        public double nextRandomVariable()
        Access the next random variable from this generator.
        Returns:
        the next random variable.
