\name{FOMC.solution}
\alias{FOMC.solution}
\title{First-Order Multi-Compartment kinetics}
\usage{
FOMC.solution(t, parent.0, alpha, beta)
}
\arguments{
\item{t}{Time.}

\item{parent.0}{Starting value for the response variable at time zero.}

\item{alpha}{Shape parameter determined by coefficient of variation of rate
constant values.}

\item{beta}{Location parameter.}
}
\value{
The value of the response variable at time \code{t}.
}
\description{
Function describing exponential decline from a defined starting value, with
a decreasing rate constant.
}
\details{
The form given here differs slightly from the original reference by
Gustafson and Holden (1990). The parameter \code{beta} corresponds to 1/beta
in the original equation.
}
\note{
The solution of the FOMC kinetic model reduces to the
  \code{\link{SFO.solution}} for large values of \code{alpha} and
  \code{beta} with \eqn{k = \frac{\beta}{\alpha}}{k = beta/alpha}.
