nlme (version 3.1-130)

summary.lme: Summarize an lme Object

Description

Additional information about the linear mixed-effects fit represented by object is extracted and included as components of object. The returned object has a print and a coef method, the latter returning the coefficient's tTtable.

Usage

"summary"(object, adjustSigma, verbose, ...)
"print"(x, verbose = FALSE, ...)

Arguments

object

an object inheriting from class "lme", representing a fitted linear mixed-effects model.

adjustSigma

an optional logical value. If TRUE and the estimation method used to obtain object was maximum likelihood, the residual standard error is multiplied by $sqrt(nobs/(nobs - npar))$, converting it to a REML-like estimate. This argument is only used when a single fitted object is passed to the function. Default is TRUE.

verbose

an optional logical value used to control the amount of output in the print.summary.lme method. Defaults to FALSE.

...

additional optional arguments passed to methods, mainly for the print method.

x

a "summary.lme" object.

Value

an object inheriting from class summary.lme with all components included in object (see lmeObject for a full description of the components) plus the following components:

Examples

fm1 <- lme(distance ~ age, Orthodont, random = ~ age | Subject)
(s1 <- summary(fm1))
## Not run: coef(s1) # the (coef | Std.E | t | P-v ) matrix
