Re: st: using varlist wildcards in anova

[Vineet Bhagwat <vineet.bhagwat@gmail.com>]

It seems to be my version of Stata.  I tried the exact same command
("anova y t* ") using the stata on my university's server and it
worked fine.

Which is weird, because on my computer's Stata, "reg y t* " and any
other command using the asterisk works fine, just -anova- that seems
to throw the error for some reason.  I'm using Stata9 on my computer
if that clarifies anything.

Anyway thanks for your help on this,

Vineet
