Greetings, I am working on a project where we are applying the Kruskal-Wallace test to some factor data to evaluate their correlation with existing grade data. I know that the grade data is nonnormal therefore we cannot rely on ANOVA or a similar parametric test. What I would like to find is a mechanism for making power calculations for the KW test given the nonparametric assumptions. My perusal of the literature has suggested that a simulation would be the best method. Can anyone point me to good examples of such simulations for KW in R? And does anyone have a favourite package for generating simulated data or conducting such tests? Thank you, Collin. [[alternative HTML version deleted]]
