In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest-posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is … See more The intuition behind the RDD is well illustrated using the evaluation of merit-based scholarships. The main problem with estimating the causal effect of such an intervention is the homogeneity of performance to the … See more The two most common approaches to estimation using an RDD are non-parametric and parametric (normally polynomial regression). Non-parametric … See more • When properly implemented and analysed, the RDD yields an unbiased estimate of the local treatment effect. The RDD can be almost as good as a randomised experiment in measuring a treatment effect. • RDD, as a quasi-experiment, … See more Fuzzy RDD The identification of causal effects hinges on the crucial assumption that there is indeed a sharp cut-off, around which there is a discontinuity in the probability of assignment from 0 to 1. In reality, however, cutoffs are … See more Regression discontinuity design requires that all potentially relevant variables besides the treatment variable and outcome variable be continuous at the point where the … See more • The estimated effects are only unbiased if the functional form of the relationship between the treatment and outcome is correctly modelled. The most popular caveats are non-linear relationships that are mistaken as a discontinuity. • Contamination by … See more • Quasi-experiment • Design of quasi-experiments See more Webrdd-package Regression Discontinuity Estimation Package Description Regression discontinuity estimation package Details rdd supports both sharp and fuzzy RDD utilizing …

WebJul 4, 2024 · I am using the Stata rdrobust command for RDD analysis, aiming to perform a two-stage analysis. The first stage is to model the probability of receiving the treatment at cut-off and the second stage is to use the predicted value of the treatment variable on my dependent variables. WebThe RDD interface is still supported, and you can get a more detailed reference at the RDD programming guide. However, we highly recommend you to switch to use Dataset, which … grant writers in atlanta georgia
