Question

Quizplus · Accepted Answer

In the regression discontinuity analysis model, the pretest is adjusted by subtracting the cutoff in order to ensure that the groups being compared are equivalent at the point where the treatment or intervention is administered. This adjustment helps to control for any pre-existing differences between the groups and to isolate the effect of the treatment on the outcome of interest. Multiplying by the reliability estimate, multiplying by β, or subtracting zo are not appropriate ways to adjust the pretest in this context.
