Martin - Yes, sorry - I should have given the full anova command. Here is
full output for a reduced data set that gives the same error:

Well, can you frame the problem in terms of an example that is accessible
to all? It is hard to create one for oneself. Your -anova- is in replay
mode, right?

Betreff: st: matvlc option not allowed after -anova-
Hi - I can't seem to get the syntax correct for the -matvlc- optin after
anova. Here's what the help file says under anova postestimation:
Syntax for test after anova
test, test(matname) [mtest[(opt)] matvlc(matname)] syntax 1
matvlc(matname), a programmer's option, saves the variance-covariance
matrix
of the linear combinations involved in the suite of tests. For the
test
Lb = c, what is returned in matname is LVL', where V is the
estimated
variance-covariance matrix of b.
But when I try the -matvlc- option, I get an error:
Can anyone tell me what's wrong?
Thanks
Al Feiveson
