MuMIn-package Multi-model inference<br />

Description<br />

Details<br />

The package MuMIn contains functions to streamline information-theoretic model selection and<br />

carry out model averaging based on the information criteria.<br />

The collection of functions includes:<br />

dredge performs automated model selection with subsets of the supplied ‘global’ model, and optional<br />

choices of other model properties (such as different link functions). The set of models<br />

may be generated either with ‘all possible’ combinations, or tailored according to the conditions<br />

specified.<br />

pdredge does the same, but can parallelize model fitting process using a cluster.<br />

model.sel creates a model selection table from hand-picked models.<br />

model.avg calculates model averaged parameters, with standard errors and confidence intervals.
