In addition to the assignment Wi and the outcome Yi, we may observe a vector of covariates or pretreatment variables denoted by ðXi; ZiÞ, where Xi is a scalar and Zi is an M-vector. A key characteristic of Xi and Zi is that they are known not to have been affected by the treatment. Both Xi and Zi are covariates, with a special role played by Xi in ...
denote the financial aid group. For simplicity, let us focus on the case with L 1⁄4 2, and a single cutoff point c. Having a score of just over c will put an applicant in a higher category and increase the chances of financial aid discontinuously compared to having a score of just below c. The outcome of interest in the Van Der Klaauw study is coll...
One important aspect of both the SRD and FRD designs is that they, at best, provide estimates of the average effect for a subpopulation, namely the subpopulation with covariate value equal to Xi 1⁄4 c. The FRD design restricts the relevant subpopulation even further to that of compliers at this value of the covariate. Without strong assumptions jus...
In the third graph, one should plot the number of observations in each bin, Nk, against the mid points bk. ~ This plot can be used to inspect whether there is a discontinuity in the distribution of the forcing variable X at the threshold. Such discontinuity would raise the question of whether the value of this covariate was manipulated by the indiv...
d0ZiÞ2, will have little effect on the expected value of the estimator for t, since conditional on X being close to c, the additional covariates Z are independent of W. The second point is that even though the presence of Z in the regression does not affect any bias when X is very close to c, in practice we often include observations with values of...
In the FRD design, there are four regression functions that need to be estimated: the expected outcome given the forcing variable, both on the left and right of the cutoff point, and the expected value of the treatment variable, again on the left and right of the cutoff point. In principle, we can use different binwidths for each of the four nonpar...
The second test is conceptually somewhat different, and unique to the RD setting. McCrary (2007) suggests testing the null hypothesis of continuity of the density of the covariate that underlies the assignment at the discontinuity point, against the alternative of a jump in the density function at that point. Again, in principle, one does not need ...
In this paper, we reviewed the literature on RD designs and discussed the implications for applied researchers interested in implementing these methods. We end the paper by providing a summary guide of steps to be followed when implementing RD designs. We start with the case of SRD, and then add a number of details specific to the case of FRD. Case...

When we discontinue, we intentionally put an end to a particular item or process, making it no longer available or in use. This term is often used in business contexts when a company decides to discontinue a product line due to various reasons, such as low demand or changing market trends.
discontinue (doing) something to stop doing, using or providing something, especially something that you have been doing, using or providing regularly. It was decided to discontinue the treatment after three months. The company has discontinued the practice of providing the staff with free lunches.
