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.
