You are correct. Only syntax 3 of -test- after -anova- (type
-help anova postestimation##test- in your Stata Viewer) allows
you to directly use a term other than residual error as the error
term.
The steps to get what you are after are found in the FAQ
http://www.stata.com/support/faqs/stat/singledof.html
(see especially the last part of the FAQ).
I agree that it would be nice if syntax 1 had an option for
specifying other error terms. It is on my list to consider for
future development.
