Dunn's test is a non-parametric pairwise multiple comparisons procedure based on rank sums, often used as a *post hoc* procedure following rejection of a Kruskal-Wallis test. The large sample reference distribution of the test statistic is derived together with a set of computational formulas for the test statistic. 2. Bước 1.
