      • LogNormal

        public LogNormal(double m,         double s)
        Create a distribution with the given mean and standard deviation.
        Parameters:
        m - the mean.
        s - the standard deviation.
    • Method Detail

      • cumulativeProbability

        public double cumulativeProbability(double x)                             throws NumericException
        The CDF for this distribution. This method returns P(X < x).
        Specified by:
        cumulativeProbability in class ContinuousDistribution
        Parameters:
        x - the value at which the CDF is evaluated.
        Returns:
        CDF for this distribution.
        Throws:
        NumericException - if the cumulative probability can not be computed.
      • getMean

        public double getMean()
        Access the mean.
        Returns:
        the mean.
      • getStandardDeviation

        public double getStandardDeviation()
        Access the standard deviation.
        Returns:
        the standard deviation.
      • setMean

        public void setMean(double m)
        Modify the mean.
        Parameters:
        m - the new mean value.
      • setStandardDeviation

        public void setStandardDeviation(double std)
        Modify the standard deviation.
        Parameters:
        std - The new standard deviation value.
