Subject: st: How to use estimated coefficients in subsequent calculations
I'm using the predict command -- predict yhat, xb -- to apply the
coefficients from estimation on one data set to another data set.
However,
I'd like to be able subtract the estimated constant term from the
prediction. How do I refer to the estimated constant (say, b[0]) to do
this: generate yhatwithoutcons=yhat-b[0]?
Thanks.
Steve
