"WebbShapley regression values match Equation 1 and are hence an additive feature attribution method. Shapley sampling values are meant to explain any model by: (1) applying sampling approximations to Equation 4, and (2) approximating the effect of removing a variable from the model by integrating over samples from the training dataset.
