Description: Implements the empirical test introduced by Yu, Ge, and
        Elwert (2026) for detecting when randomized interventional
        analogues should not be interpreted as natural mediation
        effects. The package estimates natural effects, their
        randomized interventional analogues, and TE - TE^R, the
        difference between the total effect and its randomized
        interventional analogue. Rejecting TE - TE^R = 0 falsifies the
        composite null that the natural indirect and direct effects
        equal their randomized interventional analogues. The procedure
        remains valid in settings where the natural effects themselves
        are not identified, and |TE - TE^R| provides a lower bound on
        the total divergence between the natural and randomized
        interventional decompositions.
