print.anova.lme: Print an anova.lme Object

Description

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

## S3 method for class 'anova.lme':
print(x, verbose, \dots)

Arguments

x

an object inheriting from class anova.lme, generally obtained by applying the anova.lme method to an lme object.

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").

...

some methods for this generic require additional arguments. None are used in this method.

Examples

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