\title{Indeterminate order rate equation kinetics}
\usage{
IORE.solution(t, parent_0, k__iore, N)
}
\arguments{
\item{t}{Time.}

\item{parent_0}{Starting value for the response variable at time zero.}

\item{k__iore}{Rate constant. Note that this depends on the concentration
units used.}

\item{N}{Exponent describing the nonlinearity of the rate equation}
}
\value{
The value of the response variable at time \code{t}.
}
\description{
Function describing exponential decline from a defined starting value, with
a concentration dependent rate constant.
}
\note{
The solution of the IORE kinetic model reduces to the
\code{\link{SFO.solution}} if N = 1.  The parameters of the IORE model can
be transformed to equivalent parameters of the FOMC mode - see the NAFTA
guidance for details.

\examples{

  plot(function(x) IORE.solution(x, 100, 0.2, 1.3), 0, 2, ylim = c(0, 100))

    fit.fomc <- mkinfit("FOMC", FOCUS_2006_C, quiet = TRUE)

    fit.iore.deS <- mkinfit("IORE", FOCUS_2006_C, solution_type = "deSolve", quiet = TRUE)

    print(data.frame(fit.fomc$par, fit.iore$par, fit.iore.deS$par,
                     row.names = paste("model par", 1:4)))
    print(rbind(fomc = endpoints(fit.fomc)$distimes, iore = endpoints(fit.iore)$distimes,
                iore.deS = endpoints(fit.iore)$distimes))
