%description
Implements augmented balancing weights for causal inference and linear
functional estimation based on David Bruns-Smith, Oliver Dukes, Avi
Feller, and Elizabeth L. Ogburn (2026) <doi:10.1093/jrsssb/qkaf019>.
Establishes numerical equivalence between augmented balancing weight
estimators and single linear models with weighted regression coefficients.
Provides flexible routines for double ridge (l2 balancing), double lasso
(l-infinity balancing), and generalized augmented linear outcome models.
Features cross-validation procedures for tuning outcome penalty
parameters, covariate balance, and Riesz loss. Supports robust
influence-function-based standard errors, bootstrap confidence intervals,
balance diagnostic tools, and counterfactual prediction for treatment
effects such as average treatment effect (ATE) and average treatment
effect on the treated (ATT), expanding upon the doubly robust estimation
framework established by Robins, Rotnitzky, and Zhao (1994)
<doi:10.1080/01621459.1994.10476818> and Chernozhukov, Chetverikov,
Demirer, Duflo, Hansen, Newey, and Robins (2018) <doi:10.1111/ectj.12097>.
