Hello,
Anyone familiar with robust ANOVA in R? Please help.
I am conducting a between-between-within (2 X 2 X 2) ANOVA, with the focus
on the significance of the three-way interaction. Because of very uneven sample
sizes, and the violation of covariance homogeneity, I need to use some sort of
robust ANOVA method, and I prefer bootstrap. I am aware of Rand Wilcox's
robust package that can be run in R, but although it has the bootstrap functions
for between-within ANOVA. it does not contain the bootstrap functions for
between-between-within ANOVA. Thanks a lot.
