Rdd analysis

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 …

WebJun 25, 2024 · I think the usual concerns with using time as the forcing variable in RDD are that 1.) you might not have a lot of observations near the cutoff, 2.) the treatment might be something that evolves over time so looking in a narrow window is not meaningful, 3.) serial correlation in outcome and errors 4.) endogenous timing.

WebWhat RDD does is use the fact that whether an observation is just to the left of x0 x 0 or just to the right of x0 x 0 is effectively random.
