SelectionBias

Computes bounds and sensitivity parameters as part of sensitivity analysis for selection bias. Two bounds are provided: the SV (Smith and VanderWeele) bound and the AF (assumption-free) bound. The SV bound assumes an additional dependence structure in form of a generalized M-structure whereas the AF bound holds for general assumptions in the potential outcomes framework.
