Many thanks to Nick and Austin for their replies.



You can save the coefficients to scalars e.g.

scalar intercept = _b[_cons]
scalar weightcoeff  = _b[weight]

and use those scalars in calculations later in the same session,
referring to them by name. Make sure that you don't use the same names
for scalars as for any variables No function, in the Stata sense, is
involved here.

You can -update- your Stata to 8.2 for free. See

sysuse auto, clear

gen wtsq = weight^2

regress mpg weight wtsq

predict mpghat

twoway (scatter mpg weight) (line mpghat weight, sort)

 * Let's say I'm happy with the above fitted model.

 * In future, how can I predict mpg as a function

 * In other words, I want to save the above
