Is the Wilcoxon signed-rank test with Bonferroni adjustment also an appropriate post-hoc test in this case? The paper does not suggest pairwise comparisons of all groups if one wants to test a new algorithm against existing baselines. Instead, one should only compare the new algorithm (control) to the existing ones. sample Wilcoxon test. I'll start by describing the two sample Wilcoxon test (also known as the Mann-Whitney test), since it's actually simpler than the one sample version. Suppose we're looking at the scores of 10 people on some test. Since my imagination has now failed me completely, let's pretend it's a "test of awesomeness", and there are two groups of people, "A" and "B".
The signed rank test is also commonly called the Wilcoxon signed rank test or simply the Wilcoxon test. To form the signed rank test, compute d i = X i - Y i where X and Y are the two samples. Rank the d i without regard to sign. Tied values are not included in the Wilcoxon test. After ranking, restore the sign (plus or minus) to the ranks.

PROC UNIVARIATE provides three tests for location: Student's t test, the sign test, and the Wilcoxon signed rank test. All three tests produce a test statistic for the null hypothesis that the mean or median is equal to a given value against the two-sided alternative that the mean or median is not equal to . By default, PROC UNIVARIATE sets
Wilcoxon Signed-Rank Test. The Wilcoxon Signed-Rank Test is used to see whether observations changed direction on two sets of ordinal variables. It's usefull, for example, when comparing results of questionaires with ordered scales for the same person across a period of time.
There are many non-parametric tests analogous to parametric tests in continuous variables, namely Mann-Whitney U test and independent t-test, Wilcoxon signed-rank test, and paired t-test, Kruskal Wali's test and Analysis of Variance (ANOVA), and Spearman rank correlation coefficient and Pearson product-moment coefficient.
