summary.gls: Summarize a Generalized Least Squares
Description
Additional information about the linear model fit represented
by object is extracted and included as components of
object.
Usage
# S3 method for gls
summary(object, verbose, …)
Arguments
object
an object inheriting from class "gls", representing
a generalized least squares fitted linear model.
verbose
an optional logical value used to control the amount of
output when the object is printed. Defaults to FALSE.
…
some methods for this generic require additional
arguments. None are used in this method.
Value
an object inheriting from class summary.gls with all components
included in object (see glsObject for a full
description of the components) plus the following components:
corBeta
approximate correlation matrix for the coefficients
estimates
tTable
a matrix with columns Value,
Std. Error, t-value, and p-value representing
respectively the coefficients estimates, their approximate standard
errors, the ratios between the estimates and their standard errors,
and the associated p-value under a \(t\) approximation. Rows
correspond to the different coefficients.
residuals
if more than five observations are used in the
gls fit, a vector with the minimum, first quartile, median, third
quartile, and maximum of the residuals distribution; else the
residuals.
AIC
the Akaike Information Criterion corresponding to
object.
BIC
the Bayesian Information Criterion corresponding to
object.
