When only one fitted model object is used in the call to
anova.lme
, a data frame with the estimated values, the
approximate standard errors, the z-ratios, and the p-values for the
fixed effects is printed. Otherwise, when multiple fitted objects are
being compaerd, a data frame with the degrees of freedom, the
(restricted) log-likelihood, the Akaike Information Criterion (AIC),
and the Bayesian Information Criterion (BIC) of each fitted model
object is printed. If included in
x, likelihood ratio
statistics, with associated p-values, are included in the output.
USAGE:
print(x, verbose)
REQUIRED ARGUMENTS:
x
an object inheriting from class
anova.lme,
generally obtained by applying the
anova.lme method to an
lme object.
OPTIONAL ARGUMENTS:
verbose
an optional logical value. If
TRUE, the calling
sequences for each fitted model object are printed with the rest of
the output, being omitted if
verbose = FALSE. Defaults to
attr(x, "verbose").

EXAMPLES:
fm1 <- lme(distance ~ age * Sex, Orthodont, random = ~ age | Subject)
print(anova(fm1)) # single argument form
fm2 <- update(fm1, random = ~ 1 | Subject)
print(anova(fm1, fm2)) # multiple argument form
