Hi,
I would need to find the first and last year with data for each country in a large table. There are also gap years in the middle. For example, in the attached file, the formula should give:
Albania: first year with data --> 1995
last year with data --> 2004
Belgium: first year with data --> 1995
last year with data --> 2008
Is there any way to do this rather than by hand? (I have many variables and 157 countries...)
Thanks a lot!
