\title{Simulated DEBtox Growth Data}
\format{
A data frame with 280 rows and 4 columns:
\describe{
\item{id}{Individual identifier (integer, 1--40)}
\item{concentration}{External toxicant concentration (arbitrary units)}
\item{time}{Observation time in days (0, 7, 14, \ldots, 42)}
\item{length}{Structural length in cm (with measurement error)}
}
}
\source{
Simulated with NEC \eqn{z_w = 15}, effect intensity
\eqn{b_w = 0.003}, and base DEB parameters identical to
\link{eisenia_growth}.
}
\usage{
debtox_growth
}
\description{
Simulated growth data under toxicant exposure for 4 concentration
groups (0, 20, 80, 200 arbitrary units) with 10 individuals per group
measured weekly over 6 weeks.  Designed for fitting the DEBtox (TKTD)
model in \code{\link[=bdeb_tox]{bdeb_tox()}}.  The toxicant acts through stress on
assimilation: the effective assimilation rate is reduced by a factor
\eqn{\max(1 - b_w \max(C_w - z_w, 0), \, 0)} following the DEBtox
framework of Jager et al. (2006).
