Description
I am trying to follow the suggested syntax for appending individual level files across waves into a long format. However I wish to retain some variables that are not available in all the waves.
When I try to use the syntax dofile available on the website (MERGING INDIVIDUAL FILES ACROSS WAVES INTO LONG FORMAT) I get error messages when it encounters variables that are only available in some waves (e.g. "variable a_simrace not found").
I noticed on the moodle course a command called "isvar" was proposed as a solution. However, when I try this I also get an error message, saying that "the command isvar is not recognised" (I am using Stata version 17).
What do you propose?
Thank you very much for your help
