Journal of Causal Inference 3(1): 1-24. Figure 2. RDDtools: an R package for Regression Discontinuity Design RDDtools is a new R package under development, designed to offer a set of tools to run all the steps required for a Regression Discontinuity Design (RDD) Analysis, from primary data visualisation to … Plan de la présentation La méthode de régression par discontinuité (RD) Historique et concepts importants La méthode RD en pratique Exemples d’études récentes, en particulier Lemieux et Milligan (aide sociale au Québec) et Lalive (assurance-chômage en Autriche) Pour de plus amples détails sur la méthode RD, voir Lee et Lemieux “Regression Discontinuity Designs The package includes three main functions: rdrobust, rdbwselect and rdplot. This strategy allows the researcher to target an intervention to a certain individual or group in need of the intervention without compromising internal validity. Basically, I have a list of salesman who can sell two products, product A and product B. Types of Regression Discontinuity Designs (RDD) With regard to Treatment Assignment: Sharp Design: Where the cut-point perfectly predicts who does/doesn’t receive intervention. If it is visually clear that there is a discontinuity at the cutoff then one should not be satisfied with analytic results which indicate no program effect. Introduction to Econometrics with R Chapter 9 Regression Discontinuity Design In the previous chapter we have seen how an experimental setup can be useful to recover causal effects from an OLS regression. 2015.Randomization Inference in the Regression Discontinuity Design: An Application to the Study of Party Advantages in the U.S. Senate. However, if no discontinuity is visually apparent, it may be that variability in the data is masking an effect and one must attend carefully to the analytic results.

The primary difference between a regression discontinuity design and a nonequivalent comparison group design is that in the former, assignment to intervention group is made based on the individual’s score on a pre-program measure. I am having a difficult time coming up with a functional form for a RDD I want to run. Regression Discontinuity Design. Package ‘rdrobust’ June 5, 2020 Type Package ... metric Inference in Regression-Discontinuity Designs. Derrickmiedaner. Regression-Discontinuity Design with Ten-point Treatment Effect. Local linear regressions are performed to either side of the cutpoint using the Imbens-Kalyanaraman optimal bandwidth calculation, IKbandwidth . Regression-discontinuity analysis: an alternative to the ex-post Facto experiment. Cattaneo, M. D., B. Frandsen, and R. Titiunik. Starting in the late 1990s, there has been a large number of studies in economics applying and extending RD methods. Local linear regressions are performed to either side of the cutpoint using the Imbens-Kalyanaraman optimal bandwidth calculation, IKbandwidth. Machine Learning and Modeling. Fuzzy Design: Where there exists “cross-overs” (for various reasons) With regard to . Regression Discontinuity Designs in Economics David S. Lee and Thomas Lemieux* This paper provides an introduction and “user guide” to Regression Discontinuity (RD) designs for empirical researchers. This article describes the analysis of regression-discontinuity designs (RDDs) using the R packages rdd, rdrobust, and rddtools. RDestimate supports both sharp and fuzzy RDD utilizing the AER package for 2SLS regression under the fuzzy design. Journal of Educational Psychology 51, 309–317] With the exception of a few unpublished theoretical papers, these methods did not attract much attention in the economics literature until recently. January 5, 2019, 11:15pm #1. The discontinuity could be a change in level vertically (main effect), a change in slope (interaction effect), or both. Cattaneo, M. D., B. Frandsen, and R. Titiunik. I am kind of inexperienced with RStudio, and even more so with RDD within Rstudio. R Journal 7(1): 38-51. The code I have used you can find below.
