Hi - 

I just noticed that there is no predict capability after running -oneway-.
If one knows this, there is no big problem since one could just run -anova-
instead of oneway-  and then issue the _predict- command. However if a user
is unaware that -predict- doesn't apply to -oneway- and he/she has
previously run some other estimation command, then -predict- will give
predictions, residuals, etc for the old command and not -oneway-. The user
might erroneously think these predictions are for the -oneway- analysis. I
can't think of any reason why Stata should not give predictions after
oneway, but at least, it should not allow -predict- to give the appearance
of doing something, if it is not supposed to.
