Sibling fixed effect model.

[sumedhagupta]

Hi,

Like other fixed effect models for a sibling fixed effect estimation does the data have to be in the long format with each sibling from the family listed in a different row? So for instance if in family i if there are 3 siblings a, b a and c then the data would be like:

Family ID Sibling Sibling ID X
i 1 a ...
i 2 b ...
i 3 c ...

Does this sound correct? I will really appreciate your input.

Sincerely,
Sumedha.

Yes, this is correct. xtreg, fe requires the data to be in long format.
