RD identi–cation is based on the idea that in a highly rule-based world, some rules are arbitrary and therefore provide good experiments. RD comes in two styles, fuzzy and sharp.

There are generally accepted two kinds of RDD studies. There are designs where the probability of treatment goes from 0 to 1 at the cutoff, or what is called a “sharp” design. And there are designs where the ... WebRegression discontinuity (RD) designs have become increasingly popular in political science, due to their ability to showcase causal effects under weak assumptions.

WebIn a traditional regression-discontinuity design (RDD), units are assigned to treatment and comparison conditions solely on the basis of a single cutoff score on a continuous assignment variable. The discontinuity in the functional form of the outcome at the cutoff represents the treatment effect, or the average treatment effect at the cutoff. 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 ...

WebMar 20, 2024 · For our regression discontinuity analysis, we estimated the treatment effect of statin use on incident MI using a sharp regression discontinuity for Cox models. RD models can generally be described by three main components: a score or running variable, a cutoff, and a recommended treatment. We illustrate these concepts in eFigure 1.

In reality, however, cutoffs are often not strictly implemented (e.g. exercised discretion for students who just fell short of passing the threshold) and the estimates will hence be biased. In contrast to the sharp regression discontinuity design, a fuzzy regression discontinuity design (…

WebSep 6, 2016 · RD Design Effect = 1/ [1-rho (treatment, score)^2] Where rho (treatment, score) is the correlation between assignment to treatment and the score (or running variable). Note for an RCT this correlation would be zero, whereas in a RD design treatment is determined by the score exceeding some threshold. This is for a sharp RD, with a fuzzy RD, the ...
