Subject   st: importing parameters from an alternative dataset
Date   Mon, 8 Mar 2004 23:47:06 -0000

I have a dataset for time (t) and (t+1). I estimate a system of equations of
the following form:

Y(jit) = b(jt)X(jit)  i = Individuals ; j = sectors

What I want to do is to predict Y(jit+1) using the estimated parameters
b(jt). (what would Y(t+1)-hat be haven't the prices changed)

 The dataset for (t) and (t+1) differ in sample number. Perhaps
the -ereturn- command might help however I don't know if it is possible to
"append" several regression results into Stata's system areas and then use
them in a an alternative dataset.
