I have a code that is
But I do not want to cluster, so what I should do to run the code above without cluster?
When I ignore the cluster, it says
option cluster() required
Code:
did2s depvar [if] [in] [weight], first_stage(varlist) second_stage(varlist) treatment(varname) cluster(varname)
When I ignore the cluster, it says
option cluster() required
