Discontinuity regression analysis
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. WebRegression discontinuity designs IES (2008) defines regression discontinuity designs as “designs in which participants are assigned to the intervention and the control conditions based on a cut-off score on a pre-intervention measure …
