Model utilities: Model utility functions

Description

These functions extract or calculate various values from provided fitted model objects(s). They are mainly meant for internal use, but may be also useful for end-users.

beta.weights computes standardized coefficients (beta weights) for a model;

coeffs extracts model coefficients;

getAllTerms extracts independent variable names from a model object;

coefTable extracts a table of coefficients, standard errors and, when possible, associated p-values from a model object;

model.names generates shorthand numeric names for one or several fitted models.

Usage

beta.weights(model)
coeffs(model)
getAllTerms(x, ...)
## S3 method for class 'terms':
getAllTerms(x, offset = TRUE, intercept = FALSE, ...)
coefTable(model, dispersion = NULL, ...)
tTable(model, ...) # deprecated
model.names(object, ..., labels = NULL)

Arguments

model

a fitted model object.

dispersion

the dispersion parameter. Applies to glm only. See summary.glm.

object

a fitted model object or a list of such objects.

x

a fitted model object or a formula.

offset

should offset terms be included?

intercept

should terms names include the intercept?

labels

optionally, a character vector with names of all the terms, e.g. from a global model. model.names enumerates the model terms in order of their appearance in the list and in the models. So, changing the order of the models would lead to dif

...

For model.names, more fitted model objects. In other functions often not used.

Details

The functions coeffs, getAllTerms and coefTable provide interface between the model object and model.avg (and dredge). Custom methods can be written to provide support for additional classes of models. The vignette html{/library/MuMIn/doc/gamm.pdf{Extending MuMIn's functionality}}{Extending MuMIn's functionality} describes it in more detail.
