colemanCollectivityPowerIndex: Compute Coleman Power index of a Collectivity to Act

Description

Calculates the Coleman Power index of a Collectivity to Act for a specified simple TU game. Note that in general the Coleman Power index of a Collectivity to Act is not an efficient vector, i.e. the sum of its entries is not always 1. Note also that the the Coleman Power index of a Collectivity to Act is identical for each player, i.e. the result for each player is the number of winning coalitions divided by 2^n. Hence no drawing routine for the Coleman Power index of a Collectivity to Act is provided.

Usage

colemanCollectivityPowerIndex(v)

Arguments

v

Numeric vector of length 2^n - 1 representing the values of the coalitions of a TU game with n players

Value

Coleman Power index of a Collectivity to Act for specified simple game
