# Corrected Akaike Information Criterion

### Description

This generic function calculates the small-sample corrected Akaike information criterion,
for one or several
fitted model objects for which a log-likelihood value can be obtained,
according to the formula *-2*log-likelihood +
2*npar*(nobs/(nobs-npar-2))*, where *npar* represents the
number of parameters and *nobs* the number of
observations in the fitted model.

### Usage

### Arguments

`object` |
An object of a suitable class for the AICc to be
calculated - usually a |

`...` |
Some methods for this generic function may take additional, optional arguments. At present none do. |

### Value
