FORTRAN Programs for Non-Parametric Studies

FORTRAN programs (written as subroutines) are given to perform statistical tests which are not based on any particular underlying distribution for the data. The data are entered from a calling program, and the subroutine returns either the significance level for the tests or a correlation coefficient and its significance. Tests include the runs test for randomness of data, six hypothesis tests, the sign test, the Wilcoxon matched-pairs signed-ranks test, the Friedman two-way analysis of variance, the Kolmogorov-Smirnov two-sample test, the Kruskal-Wallis one-way analysis of variance, and two correlation tests, the Spearman rank correlation and the Kendall coefficient of concordance. Examples are given for the use of all tests. (Author)
