+\description{
+ Function describing exponential decline from a defined starting value, with
+ a decreasing rate constant.
+
+ 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.
+}
+\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.
+}
+}
+\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}.
+}
+\value{
+ The value of the response variable at time \code{t}.
