aic {glmulti}

Computing an IC from a fitted model object

Description

These functions are used by glmulti to compute Information Criteria from a fitted model object. They are S4 generics, currently with methods for glm/lm objects. You may define your own methods if needed, to support other fitting functions or to use other IC.

Usage

aic(object, ...)
aicc(object, ...)
bic(object, ...)
qaic(object, ...)
qaicc(object, ...)

Arguments

object

A fitted model object.

...

Further arguments that may be useful for future methods.

Details

When using qaic or qaicc, you will need to provide an estimate of the inflation factor c. This is done through the global variable glmultiqaiccvalue. Set this varaible equal to your estimated c before running glmulti. Otherwise it will stop with a warning.

Value

The IC value of the model.
