Regression discontinuity designs: A guide to practice

The RD design takes the shape of a quasi-experimental research design with a clear structure that is devoid of randomized experimental features. Several aspects deny the RD designs an allowance for a status quo. For instance, the designs often involve serious issues that do not offer room for random experiments. See more 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 … 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 assignment of treatment (e.g. … 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 … See more The two most common approaches to estimation using an RDD are non-parametric and parametric (normally polynomial regression). Non-parametric … 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 treatment and outcome discontinuities occur. One sufficient, though not … 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 … See more WebApr 14, 2024 · The goal of the research phase is to gather as much information as possible to inform the design process and ensure that the resulting design meets the needs of its … graphnix webcams
