Hi to all,
I'm working with panel data but the data base is split in two files. In one file I have x variables from 1994 to 2002. In the second file I have the same x variables form 2003 to 2005 and y variables from 1994 to 2005.
After I merge the files, the x variables are not added into the other file. I have only missing values form 1994 to 2002 and values form 2003 to 2005. The y variables are well merged. I have tried to merge the files in both sense but the problem still remains.
The command I used is :
merge id using ESSE
Does anyone knows how can I solve this problem?.
