\title{Interface to RKPACK}
\description{
Call RKPACK routines for numerical calculations concerning the
\code{\link{ssanova0}} and \code{\link{gssanova0}} suites.
}
\usage{
sspreg0(s, q, y, method="v", varht=1)
mspreg0(s, q, y, method="v", varht=1, prec=1e-7, maxiter=30)
sspregpoi(family, s, q, y, wt, offset, method="u", varht=1, nu, prec=1e-7, maxiter=30)
mspregpoi(family, s, q, y, wt, offset, method="u", varht=1, nu, prec=1e-7, maxiter=30)
getcrdr(obj, r)
getsms(obj)
}
\details{
\code{sspreg0} is used by \code{\link{ssanova0}} to fit Gaussian
models with a single smoothing parameter. \code{mspreg0} is used to
fit Gaussian models with multiple smoothing parameters.
\code{sspregpoi} is used by \code{\link{gssanova0}} to fit non
Gaussian models with a single smoothing parameter. \code{mspregpoi}
is used to fit non Gaussian models with multiple smoothing
parameters.
\code{getcrdr} and \code{getsms} are used by
\code{\link{predict.ssanova0}} to calculate standard errors of the
fitted terms.
