Choquet integral

Description

Computes the Choquet integral of a discrete function with respect to a game. The game can be given either under the form of an object of class game, card.game or Mobius.game. If the integrand is not positive, this function computes what is known as the asymmetric Choquet integral.

Methods

object = "Mobius.game", f = "numeric"

The Choquet integral of f is computed from the Möbius transform of a game.

object = "game", f = "numeric"

The Choquet integral of f is computed from a game.

object = "card.game", f = "numeric"

The Choquet integral of f is computed from a cardinal game.

Examples

## a normalized capacity
mu <- capacity(c(0:13/13,1,1))

## and its Mobius transform
a <- Mobius(mu)

## a discrete positive function f
f <- c(0.1,0.9,0.3,0.8)

## the Choquet integral of f w.r.t mu
Choquet.integral(mu,f)
Choquet.integral(a,f)

## a similar example with a cardinal capacity
mu <- uniform.capacity(4)
Choquet.integral(mu,f)
