\section{Slots}{
 \describe{
  \item{\code{x}:}{A numeric matrix with the input data.}
  \item{\code{reference}:}{An object of \code{\linkS4class{vsn}},
    typically this would have been
    obtained from a previous fit to a set of reference arrays (data).}
  \item{\code{strata}:}{A factor of length 0 or n. If its length is
    n, then its levels correspond to different normalization strata
    (see \code{\link{vsn2}}).}
  \item{\code{ordered}:}{Logical scalar; are the rows reordered so that
    the strata are contiguous.}
  \item{\code{lts.quantile}:}{Numeric scalar, see\code{\link{vsn2}}.}
  \item{\code{subsample}:}{Integer scalar, see\code{\link{vsn2}}.}
  \item{\code{verbose}:}{Logical scalar, see\code{\link{vsn2}}.}
  \item{\code{pstart}:}{A 3D array of size (number of strata) x (number of
    columns of the data matrix) x 2 containing start parameters.}
  \item{\code{cvg.niter}:}{Integer scalar, see\code{\link{vsn2}}.}
  \item{\code{cvg.eps}:}{Numeric scalar, see\code{\link{vsn2}}.}
