Description: Estimates the local average treatment effect (LATE) and the
    local average treatment effect on the treated (LATT) using observational
    data with a binary instrument, implementing the complete estimator suite
    of Sloczynski, Uysal, and Wooldridge: the doubly robust estimators of
    Sloczynski, Uysal, and Wooldridge (2022) <doi:10.48550/arXiv.2208.01300>
    -- inverse probability weighted regression adjustment (IPWRA), inverse
    probability weighting (IPW), augmented inverse probability weighting
    (AIPW), and regression adjustment (RA) -- and the Abadie-kappa weighting
    estimators of Sloczynski, Uysal, and Wooldridge (2025)
    <doi:10.1080/07350015.2024.2332763>. Supports linear, logistic, probit,
    Poisson, and fractional (fractional-logit and fractional-probit) outcome
    and treatment models, and instrument propensity scores
    estimated by maximum likelihood, covariate balancing (CBPS), or inverse
    probability tilting (IPT). Standard errors are computed jointly for all
    estimation stages by stacking the moment conditions of every model into
    a single M-estimation system; weak-instrument-robust Fieller confidence
    sets, cluster-aware bootstrap inference, design diagnostics, and a
    doubly robust Hausman-type test of unconfoundedness are included.
    Estimates and standard errors are validated against the authors' Stata
    commands 'drlate' (Statistical Software Components S459708) and
    'kappalate' (S459257).
