The key feature of RDD is that there is a continuous variable Xi that determines who gets treatment, denoted by Di (1 if treated). By convention.

Variable X, called running variable or assignment variable, determines treatment · Units with X≥c get treatment D=1 · Units with X<c don't D=0. D=1{X≥c}.
In the sharp RD design this variable fully determines the treatment according to the cutoff rule: Di = ( 1 if Xi. X0. 0 if Xi < X0 . Xi is called the running ...
