Class SpearmanDistribution



  • public class SpearmanDistributionextends Object
    An implementation of the Spearman distribution. Uses a Singleton pattern to ensure only an instance of the class is allowed.
    • Method Detail

      • getInstance

        public static SpearmanDistribution getInstance()
        Singleton pattern access to the distribution
        Returns:
        the instance of the distribution
      • getCriticalTable

        public static Critical1KeyTable getCriticalTable()
        Gets the table of critical values of the distribution
        Returns:
        Reference to the table
      • getExactTable

        public static Aproximate1KeyTable getExactTable()
        Gets the table of the distribution
        Returns:
        Reference to the table
      • computeExactProbability

        Computes exact probability of the Spearman distribution
        Parameters:
        n - number of pairs
        T - Spearman statistic
        Returns:
        p-value computed
      • computeAproximatedProbability

        public double computeAproximatedProbability(int n,                                   double T)
        Computes approximated probability of the exact Spearman distribution
        Parameters:
        n - number of pairs
        T - Spearman statistic
        Returns:
        p-value computed
      • computeAsymptoticProbability

        public double computeAsymptoticProbability(double Z,                                  boolean dependence)
        Computes asymptotic probability of the Spearman distribution
        Parameters:
        Z - normal approximation
        dependence - true if testing positive dependence. False, if negative
        Returns:
