Description

The Akaike information criterion corrected for small sample size is a measure of the relative quality of a model. The AICc is calculated from a 'dark' object.

Usage

AICc(obj)

Arguments

obj

A dark object This object must have at least the following elements:

obj$time to calculate the number of observations
obj$Pn the number of parameters in the model
obj$val the sum of squared residual error

Value

The value returned is an indication of the information lost by fitting a particular model to the data, and is only of merit when compared to the value from another model.
