Hello all,
I try to merge two datasets [merge partner year using "E:\....dta", unique sort] of the following kind
Set1
Reporter Partner Year Value
1 A 1992
1 B 1992
1 A 1993
1 B 1993
2 A 1992
2 B 1992
2 A 1993
2 B 1993
Set2
Partner Year Index
A 1992
B 1993
What I want to do is to link the entries of Index from Set2 to each respective partner in Set1 and that for each year.
However, Stata does not want to because “partner” does not identify Set1 and there are multiple entries for the same year and partner. But even if I use “one-to-many key variables” Stata still does not connect some of the observations.
Hope somebody can help me.
Best wishes
m. baumgarten
