The AICc, or Akaike Information Criterion with small sample correction, is computed for a VGAM model.

1 | ```
AICc.vgam(mod)
``` |

`mod` |
A VGAM model object |

See references. Burnham and Anderson (2002). This correction to the AIC is derived under some assumption of normality, so it's validity may depend on there being large counts for each capture pattern so that the multivariate normal approximation to the multinomial is good.

The AIC methods for VGAM purport to have the AICc option for the
`vglm`

, but this did not seem to exist for the `vgam`

as of
October 2013.

`AICc` |
The value of the AICc |
