estimate and predict using other sample?

[River Huang]

Dear All, I have this data set test.dta (for completeness, I do not use dataex) and run the following command

reg y z x i.type ib2012.year i.asset2 if split==0

i.e., using subsample split==0. Now, I have the estimated coefficients. However, I'd like to use subsample split==1 and the estimated coefficients above to obtain predicted yy for split==1. Any suggestions? Thanks.

Very straightforward.

reg y z x i.type ib2012.year i.asset2 if split == 0

predict yy if split == 1, xb

Dear Clyde, So easy? Thanks a lot.
