Fuzzy Regression Kink Design. The case of perfect treatment compliance is usually called the sharp RD design. We introduce a generalization of the RKD the fuzzy regression kink design that allows for omitted variables in the assignment rule as well as certain types of measurement errors in the observed values of the assignment variable and the policy variable.
Robust data-driven inference in the regression-discontinuity design. And Ti ˆ Ti0 if Xi. The slope at the cutoff rather than a change in the predicted outcome.
We first show the identification of.
And Ti ˆ Ti0 if Xi. The Regression Kink Design is an extension of RDD that looks for a change in a relationship between the running variable and the outcome ie. This setup allows for imperfect compliance which in the RD literature is known as the fuzzy RD design.
