-#' Indeterminate order rate equation kinetics
-#'
-#' Function describing exponential decline from a defined starting value, with
-#' a concentration dependent rate constant.
-#'
-#' @param t Time.
-#' @param parent.0 Starting value for the response variable at time zero.
-#' @param k__iore Rate constant. Note that this depends on the concentration
-#' units used.
-#' @param N Exponent describing the nonlinearity of the rate equation
-#' @return The value of the response variable at time \code{t}.
-#' @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.
