The main goal of the paper is to discuss the generalizations of these six power indices from (2, 2)-games to (j, 2)-games for $$j\ge 3$$ j ≥ 3 . The probabilistic model and the collection of winning coalitions are trivially extendable to (j, 2)-games.
The power index of a {0, 1}-game can be interpreted as a measure of the ability of the different players to turn a losing coalition into a winning one. We consider the next power indices in SI ( N ): the Shapley–Shubik index, the Banzhaf index, the Deegan–Packel index, and the Johnston index. NettetThis is, banzhaf_index(P1) = 0.083, banzhaf_index(P2) = 0.25, banzhaf_index(P3) = 0.25 and banzhaf_index(P4) = 0.417. One can use the rest of the functions to calculate the shapley-shubik power index , the holler-packel power index , the deegan-packel power index and the johnston power index , like this (taking the same example as before):
