#' Simulated data set
#'
#' Simulated data set mimicing stand age distributions in natural, near-natural
#' non-natural forests in the setup of Mrkvička et al. (2024).
#'
#'
#' The numbers of observations in the naturalness groups and in the dominant
#' species groups correspond to the numbers of plots in on rich mineral soils in
#' Finnish Lapland in the data set analysed in Myllymäki et al. (2023).
#' The stand age values are simulated values from the quantile regression model
#' of Mrkvička et al. (2024).
#'
#' @format A \code{data.frame} containing the dominant species (three categories:
#' Broadleaf, Conifer, Mixed), naturalness (Natural, Near-natural and Non-natural)
#' and simulated stand age.
