Class Binomial

    • Constructor Detail

      • Binomial

        public Binomial()
        Default constructor. Number of trials is set to one and probability of success is set to 0.5.
      • Binomial

        public Binomial(int n,                double p)
        Create a distribution with the given number of trials and probability of success.
        Parameters:
        n - the number of trials.
        p - the probability of success.
    • Method Detail

      • cumulativeProbability

        public double cumulativeProbability(int x)                             throws NumericException
        The CDF for this distribution. This method returns P(X ≤ x).
        Specified by:
        cumulativeProbability in class DiscreteDistribution
        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.
      • getNumberOfTrials

        public int getNumberOfTrials()
        Access the number of trials.
        Returns:
        the number of trials.
      • getProbabilityOfSuccess

        public double getProbabilityOfSuccess()
        Access probability of success.
        Returns:
        the probability of success.
      • inverseCumulativeProbability

        public int inverseCumulativeProbability(double p)                                 throws NumericException
        The inverse CDF for this distribution. This method returns the largest x such that, P(X ≤ x) ≤ p. The return value must also satisfy P(X ≥ x) &ge 1 - p.
        Specified by:
        inverseCumulativeProbability in class DiscreteDistribution
        Parameters:
        p - the cumulative probability.
        Returns:
        x
        Throws:
        NumericException - if the inverse cumulative probability can not be computed.
      • probability

        public double probability(int x)
        The PMF for this distribution. This method returns P(X = x).
        Specified by:
        probability in class DiscreteDistribution
        Parameters:
        x - the value at which the probability is evaluated.
        Returns:
        PMF for this distribution.
      • setNumberOfTrials

        public void setNumberOfTrials(int n)
        Modify the number of trials.
        Parameters:
        n - the new number of trials value.
      • setProbabilityOfSuccess

        public void setProbabilityOfSuccess(double p)
        Modify probability of success.
        Parameters:
        p - the new probability of success value.
