\title{Proportional error model}
\usage{
proportional(initial, coeff, fixed = FALSE, outeq = 1)
}
\arguments{
\item{initial}{Initial value for gamma}

\item{coeff}{Vector of coefficients defining assay error polynomial}

\item{fixed}{Estimate if \code{FALSE} (default).}

\item{outeq}{The output equation number (1-based) this error model applies to.
Defaults to \code{1}. This must match the output index used in the model's \code{out}
block, e.g. \code{outeq = 2} corresponds to \code{Y[2]}.}
