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 :-)

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
