WebAs Lee and Lemieux ( 2010) note, allowing different functions on both sides of the discontinuity should be the main results in an RDD paper. To derive a regression model, first note that the observed values must be used in place of the potential outcomes: E [ Y ∣ X] = E [ Y 0 ∣ X] + ( E [ Y 1 ∣ X] − E [ Y 0 ∣ X]) D. WebRegression Discontinuity Design Idea: Find an arbitrary cutpoint c which determines the treatment assignment such that Ti = 1fXi cg Close elections as RD design (Lee et al. 2004. …

WebRegression Discontinuity Design (RDD) In the problem set we are going to practice RDD in the Lee (2008) framework. We employ the original simplified data set on the individual candidates for the US House of Representatives from 1946 to 1998. If a candidate obtains more votes than his or her competitors, he or she takes the office. kingone スタイラスペン

A simple way to estimating the treatment effect τ is to run the following linear regression. Y = α + D τ + X β + ϵ, where D ∈ [ 0, 1] and we have D = 1 if X ≥ c and D = 0 otherwise.

Web2.2 The Sharp Regression Discontinuity Design It is useful to distinguish between two general settings, the Sharp and the Fuzzy Re-gression Discontinuity (SRD and FRD from hereon) designs (e.g., Trochim, 1984, 2001; HTV).
