[R] repeated measures anova, sphericity, epsilon, etc

I have 3 questions (below). Background: I am teaching an introductory statistics course in which we are covering (among other things) repeated measures anova. This time around teaching it, we are using R for all of our computations. We are starting by covering the univariate approach to repeated

Have a look at http://cran.r-project.org/doc/Rnews/Rnews_2007-2.pdf Wow. I think my students would keel over. Anova() from the car package looks promising - I will check it out. Thanks On Tue, Mar 3, 2009 at 4:00 PM, Peter Dalgaard p.dalga...@biostat.ku.dkwrote: Paul Gribble wrote: I

[R] testing two-factor anova effects using model comparison approach with lm() and anova()

I wonder if someone could explain the behavior of the anova() and lm() functions in the following situation: I have a standard 3x2 factorial design, factorA has 3 levels, factorB has 2 levels, they are fully crossed. I have a dependent variable DV. Of course I can do the following to get the
