\title{Favor indices}

\description{Computes the favor indices of a Choquet integral from the
  underlying \bold{normalized} capacity. The capacity can be given either under the form
  of an object of class \code{capacity}, \code{card.capacity} or
  \code{Mobius.capacity}.
}

\section{Methods}{
\describe{

  \item{object = "Mobius.capacity" }{The favor indices are computed from
    the \enc{M—bius}{Mobius} transform of a capacity.}

\item{object = "capacity" }{The favor indices are computed directly from a capacity.}

\item{object = "card.capacity" }{The favor indices are computed from a cardinal capacity.}
}}

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

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

## their favor indices
favor(mu)
favor(a)

## the same with a card.capacity object
