Hi, My Stata version is 13.1. I am trying some small scale fixed effects regression to test if my main model would work. However, Stata returns these two errors. "Insufficient observations" and "varname required. My total number of observations is around 420,000. And I have checked, there are only a few missing values for the regressors and dependent variable. I checked the Stata help but it was not all that helpful xD.
