Re: st: using varlist wildcards in anova

The actual error is "t ambiguous abbreviation"....I just wrote x
mistakenly because that used to be my dummy variable name. Sorry about
that.

So I guess I'm wondering why the command

"anova y t* " won't work, it gives the error "t ambiguous abbreviation"

I created a smaller test dataset with only 3 variables, y, t1991, and
t1992 and get the same error, so I don't think it's stemming from the
dataset but how anova works.
