Class Wilcoxon

java.lang.Object

jdistlib.generic.GenericDistribution

jdistlib.Wilcoxon

public class Wilcoxon
extends jdistlib.generic.GenericDistribution

  SYNOPSIS

    #include 
    double dwilcox(double x, double m, double n, int give_log)
    double pwilcox(double x, double m, double n, int lower_tail, int log_p)
    double qwilcox(double x, double m, double n, int lower_tail, int log_p);
    double rwilcox(double m, double n)

  DESCRIPTION

    dwilcox     The density of the Wilcoxon distribution.
    pwilcox     The distribution function of the Wilcoxon distribution.
    qwilcox     The quantile function of the Wilcoxon distribution.
    rwilcox     Random variates from the Wilcoxon distribution. 

NOTE: Since the computation of Wilcoxon distribution is highly dependent on the matrix w, the dimensions of which depends on m and n (parameters of the Wilcoxon distribution), I decided to make this class as dynamic. -- Roby Joehanes
