Estimating nonparametric ANOVA

The Mann-Whitney-Wilcoxon test that we presented in the previous recipe, can be extended to multiple groups (not just 2 was before). For one-way Analysis Of Variance (ANOVA), the test that is used is called Kruskal-Wallis; we have the kruskal.test() function in base R.

For nonparametric two-way ANOVA, the Scheirer-Ray-Hare test can be used; however, the documentation is scarce, and it is not frequently used.

Getting ready

In order to run this script, you need to install the FSA and dplyr packages.

How to do it...
