Class 21: Regression Discontinuity Part II

Today we’ll work with a real-life example of RD using Medicare Advantage star ratings.


  • Explain optimal bin width and bandwidth calculations
  • Define “manipulation” of the running variable
  • Define what we mean by “covariate balance” and why it matters for RDD


  • Implement an RD strategy with Medicare Advantage star ratings
  • Test for manipulation of the running variable
  • Test for covariate balance
