Power Index Calculation Based on Advanced Capability
This power index calculator calculates the power index of Banzhaf and Shapley-Shubik, reflecting the influence of each player in the weighted voting system.
explain
Example of power index calculator: This tool calculates two important power indexes: the Banzhaf index and the Shapley-Shubik index. These indexes quantify the influence of each player in the weighted voting game, in which players have different voting weights.
