Title: Staggered Difference-in-Differences with Nonlinear Outcomes
Version: 0.2.0
Description: Supports staggered difference-in-differences designs with
    nonlinear outcomes for both panel and repeated cross-section data.
    Implements estimators for staggered treatment adoption with binary,
    count, and other nonlinear outcomes, extending Callaway and Sant'Anna
    (2021) <doi:10.1016/j.jeconom.2020.12.001> to settings with nonlinear
    outcome models such as logit, probit, and Poisson. For panel data,
    units are followed over time and 'idname' identifies repeated
    observations. For repeated cross-section data, observations are
    independent within each time period; 'idname' is optional and may
    identify survey records or households, but the estimator does not
    require the same units to appear across periods. Repeated cross-section
    estimation includes pooled quasi-maximum likelihood approaches motivated
    by Wooldridge (2023) <doi:10.1093/ectj/utad016>, with optional weighting
    and clustered inference. Methods also draw on Roth and Sant'Anna (2023)
    <doi:10.3982/ECTA19402> and Sant'Anna and Zhao (2020)
    <doi:10.1016/j.jeconom.2020.06.003>.
