I would like to merge data1 and data2:
data1,
time d1
82 1
90 0
data2,
time d2
82 1
82 1
89 0
The result should look like this
time d1 d2
82 1 1
82 . 1
89 . 0
90 0 .
You need to make sure that both data1 and data2 are sorted
according to time. Then you can use -merge-, see:
-help merge-. The do-file will look something like this:
use data2, clear
sort time
save data2, replace
use data1, clear
sort time
merge time using data2
list time d1 d2 _merge in 1/20
tab _merge
Hope this helps,
Maarten
BTW you have reached the same answer if you searched in Stata
on merge, by typing -findit merge-.
