Shapley value of a cooperative game

Given a cooperative game, the shapleyValue function computes its Shapley value.

Usage
shapleyValue(n, S = NULL, v)
Arguments
n
number of players in the cooperative game.
S
vector with all the possible coalitions. If none has been specified the function generates it automatically.
v
vector with the characteristic function of the cooperative game.
Details

The Shapley value is a solution concept in cooperative game theory proposed by Lloyd Shapley in 1953. It is obtained as the average of the marginal contributions of the players associated with all the posible orders of the players.

Value

The shapleyValue functions returns a matrix with all the marginal contributions of the players (contributions) and a vector with the Shapley value (value).
