Ali Karim <mehryar@hotmail.com> asks about a difference in the SS
for the term "round" when running

    . anova close sex round round*sex  formno|sex round*formno|sex

versus dropping the last term so that it appears as residual

    . anova close sex round round*sex  formno|sex


At first glance, I am not sure what is happening.  If possible,
could you send me the data and let me explore what is going on.
I will report back to you and the list what I find out.

The first thing I will look at is the 3-way table of round,
formno, and sex to see if some pattern there could be behind the
difference.
