Well, I wanted to answer the question brought up by Jason with this code. -h suest- states the requirement that " ... predict produce equation-level scores with the score option after an estimation command." for an estimator to be amenable to the -suest- treatment. You can check after estimation by typing
*************
db predict
*************
whether that is the case.
I hope that other listers will have more detailed explanations :-)

Betreff: Re: st: AW: RE: cross-model hypothesis test
Martin, thank you very much for the reply, I ran the following code you provided:
webuse nlswork, clear
generate age2 = age^2
generate ttl_exp2 = ttl_exp^2
generate tenure2 = tenure^2
generate byte black = race==2
xtset idcode
xtreg ln_w grade age* ttl_exp* tenure* not_smsa south if black, re
estimates store first
xtreg ln_w grade age* ttl_exp* tenure* not_smsa south if !black, re
estimates store second
suest first second
I get the following error code:
first was estimated with a non-standard vce (conventional)
r(322);
Any additional suggestions?
Thank you very much,
Joshua A. Shindell
