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
