%description
Implements difference-in-differences estimators for staggered treatment
adoption with binary, count, and other nonlinear outcomes. Extends
Callaway and Sant'Anna (2021) <doi:10.1016/j.jeconom.2020.12.001> to
handle the fundamental identification challenges that arise with nonlinear
outcome models (logit, probit, Poisson) in heterogeneous treatment timing
designs. Provides group-time average treatment effects on the treated
(ATT), aggregation schemes, and pre-treatment parallel trends tests
appropriate for nonlinear settings. Methods include doubly-robust
semiparametric estimators, nonparametric bounds, and an odds-ratio DiD
approach for binary outcomes. Methods extend Callaway and Sant'Anna (2021)
