The Kruskal and Wallis oneway analysis of variance by ranks or van der Waerden's normal score test can be employed, if the data do not meet the assumptions for oneway ANOVA. Provided that significant differences were detected by the omnibus test, one may be interested in applying posthoc tests for pairwise multiple comparisons (such as Nemenyi's test, Dunn's test, Conover's test, van der Waerden's test). Similarly, oneway ANOVA with repeated measures that is also referred to as ANOVA with unreplicated block design can also be conducted via the FriedmanTest or the Quadetest. The consequent posthoc pairwise multiple comparison tests according to Nemenyi, Conover and Quade are also provided in this package. Finally Durbin's test for a twoway balanced incomplete block design (BIBD) is also given in this package.
