Hi,
I need to fill in my descriptive statistic analysis sample, and thus I need to count the number of countries in the data set. However, I don't know a clever way to do this? I'm using GEM data, so I have a lot of observations (around 144.000) in a lot of countries. The variable name is country, but it's not a variable in my regression. What command should I use? I couldn't find it on the internet...
Thanks in advance!
Kind regards,
Josephine
