\title{Class "grpl.model": Group Lasso Models}
\description{Objects of class "grpl.model" define link function, negative
log-likelihood and corresponding gradient and Hessian for the model to
be used in a Group Lasso problem.}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{grpl.model(...)}}
\section{Slots}{
\describe{
\item{\code{invlink}}{a function with arguments \code{eta}
implementing the inverse link function.}
\item{\code{nloglik}}{a function with arguments \code{y}, \code{mu} and
\code{weights} implementing the \emph{negative}
log-likelihood function.}
\item{\code{ngradient}}{a function with arguments \code{x}, \code{y},
\code{mu} and \code{weights}
implementing the \emph{negative} gradient of the log-likelihood function.}
\item{\code{nhessian}}{a function with arguments \code{x}, \code{mu} and
\code{weights} implementing the \emph{negative} hessian of the
log-likelihood function.}
\item{\code{check}}{a function with argument \code{y} to check
whether the response has the correct format.}
\item{\code{name}}{a character name}
\item{\code{comment}}{a character comment}
