Package: sccic Type: Package Title: Synthetic Control Changes-in-Changes Estimator Version: 0.1.0 Authors@R: c( person("Neil", "Hwang", role = c("aut", "cre"), email = "neil.hwang@bcc.cuny.edu")) Description: Implements the Changes-in-Changes (CIC) estimator of Athey and Imbens (2006) combined with synthetic control methods. Provides nonparametric estimation of the entire counterfactual distribution of outcomes for a treated group, allowing evaluation of average, quantile, and distributional treatment effects. Synthetic control weights are constructed via elastic net regularization to handle settings with many potential control units.
