Hi all, I am trying to use the user-contributed synth to estimate with synthetic control method. I am running Stata 16 on Windows 10. This is the smoking.dta provided by the authors as an example dataset:
Everything runs fine unless I specify the nested option. If I do, I get the error message that I show below:
I have updated my version of Stata and my ado files, but that did not solve the issue. Before contacting the authors directly, I would like to know if anyone else has encountered this issue and knows of a solution.
Thanks!
