Abstract

In this article, we introduce the Stata (and R) packagerdmulti, which consists of three commands (rdmc, rdmcplot, rdms ) for analyzing regression-discontinuity (RD) designs with multiple cutoffs or multiple scores. The commandrdmc applies to noncumulative and cumulative multicutoff RD settings. It calculates pooled and cutoff-specific RD treatment effects and provides robust biascorrected inference procedures. Postestimation and inference is allowed. The commandrdmcplot offers RD plots for multicutoff settings. Finally, the commandrdms concerns multiscore settings, covering in particular cumulative cutoffs and two running variable contexts. It also calculates pooled and cutoff-specific RD treatment effects, provides robust bias-corrected inference procedures, and allows for postestimation and inference. These commands use the Stata (and R) packagerdrobust for plotting, estimation, and inference. Companion R functions with the same syntax and capabilities are provided.
