WebRegression: conditional independence assumption E[Y 0ijX i,D i] = E[Y 0ijX i]. Once we control for a confounder X i, treatment assignment is as good as random. The key to the RD … The intuition behind the RDD is well illustrated using the evaluation of merit-based scholarships. The main problem with estimating the causal effect of such an intervention is the homogeneity of performance to the assignment of treatment (e.g. scholarship award). Since high-performing students are more likely to be awarded the merit scholarship and continue performing well at the same time, comparing the outcomes of awardees and non-recipients would lead to an upward bi…
