Question

Quizplus · Accepted Answer

A basic regression discontinuity analysis model includes three terms: a constant term, a treatment indicator variable, and a covariate(s) or bandwidth term. The constant term captures the intercept of the regression line, the treatment indicator variable captures the effect of the treatment on the outcome, and the covariate(s) or bandwidth term controls for any systematic differences between the treatment and control groups that are a function of the assignment rule. Adding more terms can enhance the model, but the basic model requires only three terms.
