Webresults of an RDD analysis of the incumbency advantage in the U.S. House. Section 4 concludes. 2. Random assignment from non-random selection In a RDD the researcher knows that treatment is given to individuals if and only if an observed covariate V crosses a known threshold v 0. WebThe basic RD analysis involves five steps: 1. Transform the Pretest. The analysis begins by subtracting the cutoff value from each pretest score, creating the modified pretest term shown in Figure 7. This is done in order to set the intercept equal to the cutoff value. How does this work?
