nonNormalizedBanzhafIndex: Compute non-normalized Banzhaf index

Description

non-normalized Banzhaf index for a specified simple game, see formula (7.5) on p. 119 of the book by Chakravarty, Mitra and Sarkar

Usage

nonNormalizedBanzhafIndex(v)

Arguments

v

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

Value

The return value is a vector which contains the non-normalized Banzhaf index for each player.
