How to know the sample of countries taken in an analysis!

[Abdullah Ijaz]

Hi !

This may sound like a silly question. I am working on a panel data with 140 countries. However, when I run regression analysis, it takes into account only 120 countries. I understand this may happen due to presence of missing values. I have many variables. How will I know the subsample of 120 countries that has been taken into regression estimate?


Looking forward to the answer!

The sample used in a regression is stored in e(sample), so you could do something like this:

reg y x
tab country if e(sample)
