\title{Assessing Smoothing Spline ANOVA Fits with Non Gaussian Responses}
\usage{
summary[.gssanova](obj, diagnostics=FALSE)
}
\arguments{
\item{obj}{an object of class \code{"gssanova"}.}
\item{diagnostics}{a logical flag.}
}
\description{
\code{summary.gssanova} calculates various summaries of smoothing
spline ANOVA fits with non Gaussian responses.
}
\value{
\code{summary.gssanova} returns a list object of \code{\link{class}}
\code{"summary.gssanova"} consisting of the following components.
The entries \code{kappa}, \code{cosines}, and \code{roughness} are
only calculated for \code{diagnostics=TRUE}.
\item{call}{the fitting call.}
\item{family}{the error distribution.}
\item{method}{the smoothing parameter selection method.}
\item{dispersion}{the assumed or estimated dispersion parameter.}
\item{iter}{the number of performance-oriented iterations performed.}
\item{fitted}{the fitted values on the scale of link.}
\item{residuals}{the working residuals.}
\item{rss}{the residual sum of squares.}
\item{dev.resid}{the deviance residuals.}
\item{deviance}{the deviance of the fit.}
\item{dev.null}{the deviance of the null model.}
\item{penalty}{the penalty associated with the fit.}
\item{kappa}{the concurvity diagnostics for model terms. These are
virtually the variance inflation factors of a retrospective
linear model.}
\item{cosines}{the cosine diagnostics for practical significance of
the model terms.}
\item{roughness}{the roughness of individual model terms as
percentages of the overall roughness, which is proportional to
\code{penalty}.}
