Between Estimators
The between groups estimator is the regression of the cross section means of 
on the cross section means of 
. In other words, you fit the following regression:
![\[ \bar{\mi {y}}_\mi {i \cdot } = \bar{\mi {\mb {x}}}_\mi {i \cdot }{\beta }^{BG} + \eta _\mi {i} \]](images/etsug_panel0248.png){kind=small} |
The between time periods estimator is the regression of the time means of 
on the time means of . In other words, you fit the following regression:
![\[ \bar{\mi {y}}_\mi {\cdot t} = \bar{\mi {\mb {x}}}_\mi {\cdot t}{\beta }^{BT} + \zeta _\mi {t} \]](images/etsug_panel0250.png){kind=small} |
In either case, the error is assumed to be normally distributed with mean zero and a constant variance.
