Dear Yung-jin,

sorry I'm a bit late because I missed your post.

Here are the complete ANOVA tables (the F-tests were already contained in the post above) from Proc GLM:

Type I sum of squares are not contained by default. If you need them, let me know. In case of balanced data they are same as type III, isn't it?
