entropy-methods | R Documentation |

Computes the normalized entropy of a capacity. The capacity
can be given either under the form of an object of class
`capacity`

, `card.capacity`

or `Mobius.capacity`

.

- object = "Mobius.capacity"
The normalized entropy is computed from the Möbius transform of a capacity.

- object = "capacity"
The normalized entropy is computed directly from a capacity.

- object = "card.capacity"
The normalized entropy is computed from a cardinal capacity.

## its Mobius transform
a <- Mobius(mu)
## their normalized entropy
