summary.galamm: Summarizing GALAMM fits

Description

Summary method for class "galamm".

Usage

# S3 method for galamm
summary(object, ...)

Value

A list of summary statistics of the fitted model of class summary.galamm, containing the following elements:

• AICtab a table of model fit measures, returned by llikAIC.

• call the matched call used when fitting the model.

• fixef a matrix with fixed effect estimated, returned by fixef.

• gam List containing information about smooth terms in the model. If no smooth terms are contained in the model, then it is a list of length zero.

• model a list with various elements related to the model setup and fit. See ?galamm for details.

• parameters A list object with model parameters and related information. See ?galamm for details.

• Lambda An object containing the estimated factor loadings. Returned from factor_loadings.galamm. If there are no estimated factor loadings, then this object is NULL.

• random_effects a list containing the random effects. See ?galamm for details.

• VarCorr An object of class VarCorr.galamm, returned from VarCorr.galamm.

• weights An object containing information about estimated variance functions, when there are heteroscedastic residuals. Otherwise the object is NULL.

Arguments

Author

Some of the code for producing summary information has been derived from the summary methods of mgcv (author: Simon Wood) and lme4 batesFittingLinearMixedEffects2015galamm (authors: Douglas M. Bates, Martin Maechler, Ben Bolker, and Steve Walker).
