Sarah Edgington <[email protected]> asked why -teffects aipw- does not
estimate the average treatment effect on the treated (ATET).
-teffects aipw- does not estimate the ATET because the estimating equation
was not worked out when we implemented -teffects-. The sentence that Sarah
found on page 63 was not intended to be there and it shall be removed.
(Thank you.) The the augmented inverse probability-weighted (AIPW)
estimator for the ATET uses a different estimation equation, not just a
sample restriction, and that is why -teffects aipw- does not estimate the
ATET.
