did_imputation estimator

[jette leonie]

Hello everyone,

I'm new to Stata and running into the same problem over and over again with the Borusyak (did_imputation) estimator. I tried many different specification and always get the respond of 'too few variables specified'. Does anyone have an idea how I can solve this (or what I'm doing wrong in the syntax)?

. did_imputation ln_incearnpce_taxi uber, group(met2013) time(year) cluster(met2013) fe(_Iyear_2010 _Iyear_2011 _Iyear_2012 _Iyear_2013 _I
> year_2014 _Iyear_2015)
too few variables specified
r(102);

. did_imputation ln_incearnpce_taxi uber, group(met2013) time(year) cluster(met2013)
