This means that it can be thought of as a decomposition of the total R2 into components associated with each predictor.

WebbBased on the decomposition (9), the Shapley values and in-teraction indices are computed as follows. By linearity, the Shapley values can be computed summandwise, i.e. ϕ U(v) = X [A,B] ϕ U(v [A,B]·1 ). (11) So the complexity of computing the Shapley value is the complexity of computing ϕ U(v [A,B]·1 ) times the num-ber of intervals.
