#' Toxicity study with two strains of ceriodaphnia.
#'
#' Data from a study of the effect of varying concentrations of a component of jet engine fuel on reproduction of two strains \emph{Ceriodaphnia}. 
#'
#' @format A data frame with 70 observations and three variables:
#' \describe{
#'    \item{count:}{number of organisms}
#'    \item{concentration:}{percent concentration of a component of jet engine fuel}
#'    \item{strain:}{strain of \emph{Ceriodaphnia}}
#' }
#' 
#' @note No original source for the data is given so they are presumed to be simulated.
