Hypothesis Testing in Regression Discontinuity Designs

• In Event: Advanced Topics in Multiple Regression Analysis

Abstract

The regression-discontinuity design (RD) is a powerful methodological alternative to the experimental design when unable to randomly assign subjects. RD is also a better alternative than the quasi-experimental design. The RD design involves testing post-test differences between the experimental and comparison group regression lines at the cutoff point for statistical significance. Two different hypothesis testing approaches will be presented and explained.
