This function calculates weighted means of covariates where weights in inverse propensity weights and then examines the differences in the weighted means across treated and control units as a diagnostic for covariate balance.
This function implements three estimators for the population ATE— a regression estimator, an inverse propensity weighted (IPW) estimator, and an augmented inverse propensity weighted (AIPW) estimator— using generalized additive models.
