Class Exponential

    • Constructor Detail

      • Exponential

        public Exponential()
        Default constructor. Mean is set to 1.
      • Exponential

        public Exponential(double m)
        Create a distribution with the given mean.
        Parameters:
        m - the mean.
    • Method Detail

      • cumulativeProbability

        public double cumulativeProbability(double x)
        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.
      • getMean

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

        public double inverseCumulativeProbability(double p)
        The inverse CDF for this distribution. This method returns x such that, P(X < x) = p.
        Specified by:
        inverseCumulativeProbability in class ContinuousDistribution
        Parameters:
        p - the cumulative probability.
        Returns:
        x
      • setMean

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