Subject: st: How to generate "total" observation?
Hi all,
I have a (possible) dummy question. I have a panel data set like the following:
id year var1
01 2000 10
01 2001 20
02 2000 15
02 2001 25
I want to create a new observations, with id=03, that sum the var1
over the other ids. Obviously, I'm no going to use this observations
to make some estimation, but total statistics. How can I generate this
aditional observations.
Thanks
