    • Method Detail

      • cumulativeProbability

        public abstract double cumulativeProbability(int x)                                      throws NumericException
        The CDF for this distribution. This method returns P(X ≤ x).
        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.
      • inverseCumulativeProbability

        public abstract int inverseCumulativeProbability(double p)                                          throws NumericException
        The inverse CDF for this distribution. This method returns the largest x such that, P(X ≤ x) ≤ p.
        Parameters:
        p - the cumulative probability.
        Returns:
        x
        Throws:
        NumericException - if the inverse cumulative probability can not be computed.
      • probability

        public abstract double probability(int x)                            throws NumericException
        The PMF for this distribution. This method returns P(X = x).
        Parameters:
        x - the value at which the probability is evaluated.
        Returns:
        PMF for this distribution.
        Throws:
        NumericException - if the probability can not be computed.
