banzhafValue {CoopGame} | R Documentation |
banzhafValue computes the Banzhaf value for a specified TU game
The Banzhaf value itself is an alternative to the Shapley value.
Conceptually, the Banzhaf value is very similar to the Shapley value.
Its main difference from the Shapley value is that the Banzhaf value is coalition
based rather than permutation based.
Note that in general the Banzhaf vector is not efficient!
In this sense this implementation of the Banzhaf value could also
be referred to as the non-normalized Banzhaf value, see formula (20.6) in
on p. 368 of the book by Hans Peters (2015).
banzhafValue(v)
v |
Numeric vector of length 2^n - 1 representing the values of the coalitions of a TU game with n players |
The return value is a numeric vector which contains the Banzhaf value for each player.
