Additional information about the linear model fit represented
by object
is extracted and included as components of
object
.
## S3 method for class 'gls': summary(object, verbose, ...)
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. |
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 data frame 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 . |
