One of the first advantages of the regression-discontinuity design is that it might possibly sometimes be implemented in conditions during which a randomized experiment can’t be used. When it may be applied, a randomized experiment is prone to be superior to a regression-discontinuity design. However, a regression-discontinuity design is prone to produce far more credible results than nonequivalent group or correlational designs.
