Although this should go to CrossValidated (sorry, this was my first post here and I didn't know about the different sites!), one more follow-up: if the intercept is only changing the comparison of factor levels to one another, the difference in ANOVA results are strictly due to the differences in DF, right? If so, why bother with eliminating the intercept when you could compare terms with a post-hoc test? | |
