List of model classes accepted by model.avg, model.sel,
and dredge.
Fitted model objects that can be used with model selection and model averaging functions include those produced by:
glmmadmb (glmmADMB
from R-Forge);
asreml (non-free commercial package asreml; allows only for
REML comparisons);
functions from package unmarked (within the class
"unmarkedFit");
mark and related functions (class mark from package
RMark). Currently dredge can only manipulate formula
element of the argument model.parameters, keeping its other elements
intact.
Generalized Estimation Equation model implementations:
geeglm from package geepack,
gee from gee,
geem from geeM,
and yags from yags (from
R-Forge) can be used with QIC as the selection criterion.
Other classes are also likely to be supported, in particular if they inherit
from one of the above classes. In general, the models averaged with
model.avg may belong to different types (e.g. glm and gam),
provided they use the same data and response, and if it is valid to do so.
This applies also to constructing model selection tables with model.sel.
