Dear Stata-listers,
I have a variable var1 which ranks the performance of 140 countries
for 15 years. I want to examine whether another categorical variable
var2 has an effect on the performance ranking using the available
panel data. Can you suggest a way?
id t var1 var2
1 1 1 1
2 1 4 0
3 1 46 1
4 1 140 1
. . . . . . . .
1 2 2 1
2 2 5 0
3 2 44 1
4 2 139 1
Regards,
Pavlos
