Hi,

I have a dataset of 318 local authorities and am running a fixed effects regression.
However when I run the regression Stata only performs this for 311 observations.
I ran the command
tab acode if !e(sample)
However it is still not obvious why 7 of these local authorities (acode) have been excluded, is there a way to find out why/are there common reasons why? I have looked at the dataset and it is not missing any observations?
Thank You
