Re: st: Combining and repeating value from another dataset

[Michael LeGower <mjl88@pitt.edu>]

And it seems like if you wanted to do that dynamically (i.e. you have a 
bunch of these dataset pairs and you don't want to have to manually 
retrieve all of the values of e for each Y dataset), you could do 
something like the following:

use Y.dta
scalar e_value = e[1]
use X.dta, clear
gen e = e_value
