There exists an arbitrarily small bandwidth of the cutoff within which. 1. f (𝑥) - i.e. the function that describes 𝑌0𝑖 - is smooth at the cutoff, i.e. nothing other than treatment status is discontinuous in the analysis interval. 2. WebOct 6, 2024 · In practice, the assignment rule can be deterministic or probabilistic (see Hahn et al., 2001). If deterministic, the regression discontinuity takes a sharp design; if probabilistic, the regression discontinuity takes a fuzzy design. Sharp RDD. In sharp designs, the probability of treatment changes from 0 to 1 at the cutoff.
