rdrobust: An R Package for Robust Nonparametric Inference in Regression-Discontinuity Designs
نویسندگان
چکیده
This article describes the R package rdrobust, which provides data-driven graphical and inference procedures for RD designs. The package includes three main functions: rdrobust, rdbwselect and rdplot. The first function (rdrobust) implements conventional local-polynomial RD treatment effect point estimators and confidence intervals, as well as robust bias-corrected confidence intervals, for average treatment effects at the cutoff. This function covers sharp RD, sharp kink RD, fuzzy RD and fuzzy kink RD designs, among other possibilities. The second function (rdbwselect) implements several bandwidth selectors proposed in the RD literature. The third function (rdplot) provides data-driven optimal choices of evenly-spaced and quantile-spaced partition sizes, which are used to implement several data-driven RD plots.

Robust Data-Driven Inference in the Regression-Discontinuity Design
This article introduces three Stata commands to conduct “robust” data-driven statistical inference in the regression-discontinuity (RD) design. First, we present the command rdrobust that implements the robust bias-corrected confidence intervals for sharp RD treatment effects proposed in Calonico, Cattaneo, and Titiunik (2012). This command also implements other conventional nonparametric RD tr...
متن کاملIdentifying Causal Marketing Mix Effects Using a Regression Discontinuity Design
We discuss how regression discontinuity designs arise naturally in settings where firms target marketing activity at consumers, and illustrate how this aspect may be exploited for econometric inference of causal effects of marketing effort. Our main insight is to use commonly observed discontinuities and kinks in the heuristics by which firms target such marketing activity to consumers for nonp...

متن کاملnprobust: Nonparametric Kernel-Based Estimation and Robust Bias-Corrected Inference∗
Nonparametric kernel density and local polynomial regression estimators are very popular in Statistics, Economics, and many other disciplines. They are routinely employed in applied work, either as part of the main empirical analysis or as a preliminary ingredient entering some other estimation or inference procedure. This article describes the main methodological and numerical features of the ...
