Mobius-methods: The Mbius transform

Description

Computes the Mbius transform of a set function. The Mbius transform is the inverse of the zeta transform.

Methods

object = "capacity"

Returns an object of class Mobius.capacity.

object = "card.set.func"

Returns an object of class Mobius.card.set.func.

object = "game"

Returns an object of class Mobius.game.

object = "set.func"

Returns an object of class Mobius.set.func.

Examples

## a capacity
mu <- capacity(0:15)
mu

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

## its zeta transform
zeta(a)

## a similar example with a game object
mu <- game(c(0,-2:12))
mu
Mobius(mu)
zeta(Mobius(mu))

## a similar example with a set.func object
mu <- set.func(-7:8)
mu
Mobius(mu)
zeta(Mobius(mu))

## a similar example with a card.set.func object
mu <- card.set.func(-3:4)
mu
Mobius(mu)
zeta(Mobius(mu))
