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

In practice, this implicit assumption of our analysis may not hold and below we discuss how we might detect deviations from this assumption and what they mean for causal analysis.
