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.
aic(object, ...)
aicc(object, ...)
bic(object, ...)
qaic(object, ...)
qaicc(object, ...)
A fitted model object.
Further arguments that may be useful for future methods.
The IC value of the model.
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.
