st: Merge data
I've previously merged columns from A.dta to B.dta, but somehow the results
of those merged columns are not the same.
I'm trying to merge one more time. I can't seem to use -merge- anymore, but
there is apparently another command called -update-. Anybody got suggestions
as to how to go about this?
Should I drop those columns of interest to me in the master dataset first?
Or should I sort rename the sorting variables, and simply use -merge- again?
Help much appareciated.
Thanks in advance!
