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.https://github.com/r-universe/neilhwang/actions/runs/39409919173Mon, 30 Mar 2026 15:56:58 GMTsccic0.1.0successhttps://neilhwang.r-universe.devhttps://github.com/neilhwang/sccicsccic-intro.Rmdsccic-intro.htmlIntroduction to sccic2026-03-30 15:55:472026-03-30 15:55:47
