how to filtrate part of observations of panel data?

[tony]

Hi there,
Say I have a panel data including 100 countries and 30 years, and I want to filtrate the data some countries, for example, USA, UK, etc.
Then, how to do that?
Many thanks.

Code: Select all

smpl if country = "USA" or country = "UK"

If you have lots of countries you want to include you can use:
[code]
smpl if @inlist(country, “UK USA “”New Zealand”” Germany”)
