I think you are right..I didnt explain it well.
This is purly a data arranging issue, pre-estimation. The
second set of Reporter Partner Year to be dropped once Var2
data is aligned with corresponding the Year Report Partener (frist 3 columns)..for example A D 1986 .4 should be aligned with 2nd row 2..and C A 1989 .3 should be in row 6..its a question of how to do this for a large dataset..
Reporter Partner Year Var1 Reporter Partner Year Var2
> A B 1985 10 A D 1986 .4

> A D 1986 14
> B A 1985 15
> B C 1985 18
> C A 1989 20
