\title{Summarizing ARMA Model Fits}
\description{
Methods for creating and printing summaries of ARMA model fits.
}
\usage{
\method{summary}{arma}(object, \dots)
\method{print}{summary.arma}(x, digits = max(3, getOption("digits") - 3),
signif.stars = getOption("show.signif.stars"), \dots)
}
\arguments{
\item{object}{an object of class \code{"arma"}; usually, a result of a
call to \code{\link{arma}}.}
\item{x}{an object of class \code{"summary.arma"}; usually, a result
of a call to the summary method for objects of class \code{"arma"}.}
\item{digits, signif.stars}{see \code{\link{printCoefmat}}.}
\item{\dots}{further arguments passed to or from other methods.}
}
\details{
The summary method computes the asymptotic standard errors of the
coefficient estimates from the numerically differentiated Hessian
matrix approximation. The AIC is computed from the conditional
sum-of-squared errors and not from the true maximum likelihood
function. That may be problematic.

\value{
A list of class \code{"summary.arma"}.
