Hi Dear,

If we have to run t tests of two groups of countries. Both groups of countries consist of different number of countries. For example, group one has 6 countries and group two has 3 countries. Data for each country is for the same 30 years. The t tests have to be conducted at the group level. Do you think unpaired t test can work for such type of panel data set?

Or it will be a case of paired two-sample t test?

Are there any specific Stata commands for it?

Thank you.
