summary.lme {nlme} | R Documentation |
Additional information about the linear mixed-effects fit represented
by object
is extracted and included as components of
object
. The returned object is suitable for printing with the
print.summary.lme
method.
summary(object, verbose)
object |
an object inheriting from class lme , representing
a fitted linear mixed-effects model. |
verbose |
an optional logical value used to control the amount of
output in the print.summary.lme method. Defaults to
FALSE . |
summary.lme
with all components
included in object
(see lmeObject
for a full
description of the components) plus the following components:
corFixed |
approximate correlation matrix for the fixed effects estimates |
tTable |
a data frame with columns Value ,
Std. Error , DF , t-value , and p-value representing
respectively the fixed effects estimates, their approximate standard
errors, the denominator degrees of freedom, the ratios between the
estimates and their standard errors,
and the associated p-value from a t distribution. Rows
correspond to the different fixed effects. |
residuals |
if more than five observations are used in the
lme fit, a vector with the minimum, first quartile, median, third
quartile, and maximum of the innermost grouping level residuals
distribution; else the innermost grouping level residuals. |
AIC |
the Akaike Information Criterion corresponding to
object . |
BIC |
the Bayesian Information Criterion corresponding to
object . |
