%description
Implements the locally efficient doubly robust difference-in-differences
(DiD) estimators for the average treatment effect proposed by Sant'Anna
and Zhao (2020) <doi:10.1016/j.jeconom.2020.06.003>. The estimator
combines inverse probability weighting and outcome regression estimators
(also implemented in the package) to form estimators with more attractive
statistical properties. Two different estimation methods can be used to
estimate the nuisance functions.
