\title{ Summarizing model fits for segmented mixed-effects regression }
\description{
summary method for class \code{segmented.lme}.
}
\usage{
\method{summary}{segmented.lme}(object, .vcov=NULL, digits = max(3, getOption("digits") - 3), ...)
%\method{print}{summary.segmented}(x, short=x$short, var.diff=x$var.diff,
% digits = max(3, getOption("digits") - 3),
% signif.stars = getOption("show.signif.stars"),...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{object}{ Object of class "segmented.lme". }
\item{.vcov}{ Optional. The full covariance matrix for the parameter estimates. If provided, standard errors are computed (and displayed) according to this matrix.}
% \item{x}{a \code{summary.segmented} object produced by \code{summary.segmented()}.}
\item{digits}{controls number of digits printed in output.}
% \item{signif.stars}{logical, should stars be printed on summary tables of coefficients?}
\item{\dots}{ further arguments. }
}
\details{
%If \code{short=TRUE} only coefficients of the segmented relationships are printed.
The function summarizes and prints the most relevant information on the segmented mixed fit. The output is similar to that returned by \code{print.summary.lme}
}
\value{
A list (similar to one returned by \code{segmented.lm}) with estimates of the variance components, and point estimates, standard errors, DF, t-value and p-value for the fixed effects. p-values for the variables \code{U} and \code{G0} are omitted as pointless.
% \item{Ttable }{estimates and standard errors of the model parameters. This is similar
% to the matrix \code{coefficients} returned by \code{summary.lm} or \code{summary.glm},
% but without the rows corresponding to the breakpoints. Even the p-values relevant to the
% difference-in-slope parameters have been replaced by NA, since they are meaningless in
% this case, see \code{\link{davies.test}}.}
% \item{cov.var.diff}{if \code{var.diff=TRUE}, the covaraince matrix accounting for heteroscedastic errors.}
% \item{sigma.new}{if \code{var.diff=TRUE}, the square root of the estimated error variances in each interval.}
% \item{df.new}{if \code{var.diff=TRUE}, the residual degrees of freedom in each interval.}
