WebPROC NPAR1WAY provides Hodges-Lehmann estimation of the location shift between two samples, including asymptotic (Moses) and exact confidence limits. In addition, PROC NPAR1WAY produces the following tests for scale differences: Siegel-Tukey test, Ansari-Bradley test, Klotz test, and Mood test. WebDetails - pairwise_wilcox_test() applies the standard two sample Wilcoxon test to all possible pairs of groups. This method calls the wilcox.test(), so extra arguments are accepted. - If a list of comparisons is specified, the result of the pairwise tests is filtered to keep only the comparisons of interest.The p-value is adjusted after filtering.
