QIC 45<br />
Arguments<br />
Value<br />
Note<br />
object<br />
a fitted model object of class "gee", "geepack", "geem" or "yags".<br />
... for QIC and QIC u , optionally more fitted model objects.<br />
typeR<br />
logical, whether to calculate QIC(R). QIC(R) is based on quasi-likelihood of a<br />
working correlation R model. Defaults to FALSE, and QIC(I) based on independence<br />
model is returned.<br />
If just one object is provided, returns a numeric value with the corresponding QIC; if more than one<br />
object are provided, returns a data.frame with rows corresponding to the objects and one column<br />
representing QIC or QIC u .<br />
This implementation is based partly on (revised) code from packages yags (R-Forge) and ape.<br />

Methods exist for gee (package gee), geeglm (geepack), geem (geeM), and yags (yags on R-Forge).<br />
yags and compar.gee from package ape both provide QIC values.<br />
