In a sharp regression discontinuity design
WebWe use a regression-discontinuity design to study the effects of double blocking sixth-grade students in reading and mathematics on their achievement across three years of middle school. To identify the effect of the intervention , we use sharp cutoffs in the test scores used to assign students to double blocking. We find large, positive, and ... WebJul 1, 2024 · Abstract. We study regression discontinuity designs when covariates are included in the estimation. We examine local polynomial estimators that include discrete or continuous covariates in an additive separable way, but without imposing any parametric restrictions on the underlying population regression functions. We recommend a …

WebRegression discontinuity (RDD) is a research design for the purposes of causal inference. It can be used in cases where treatment is assigned based on a cutoff value of a “running … WebIn the absence of a randomized control trial, regression discontinuity (RD) designs can produce plausible estimates of the treatment effect on an outcome for individuals near a cutoff score. In the standard RD design, individuals with rating scores higher than some exogenously determined cutoff score are assigned to one treatment condition; those with …
