Is there a reason why -test- after -anova , sequential- uses partial sums of 
squares?

sysuse bpwide, clear
anova bp_after sex agegrp sex*agegrp, sequential
test agegrp

I'm trying to -test- based upon so-called SAS Type II sums of squares, here.  

Now, I can manually calculate the Type II sums of squares from the -ereturn- 
results for two -anova- runs (the difference between e(mss) from -anova depvar 
A B, sequential- and that from -anova depvar A, sequential-) to do the test, 
but it would seem more natural to have -test- acknowledge the options of the 
-anova- command that it refers to . . .
