\name{IORE.solution}
\alias{IORE.solution}
\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.
}
