Dear Stata-listers:
I want to generate a variable during (preserve - restore) and want to
use that after restoring the data. When I will restore data the variable
will be dropped automatically. How can I keep the variable?
The data is time series and a simple version of my program is as follows:
preserve
keep if year == 2000
factor x1 x2 x3
predict var1
restore
gsort -year
replace var1= var1[_n-1] if var1 >= .
xtset country year
xtreg dep var1 controls
The problem in this program is that after restoring the data I will not
have var1 anymore. What can be a possible solution?
Thanks and best regards,
Tanveer
