#' @description
#' Wheat yield.
#' The data set consists of 45 measurements of wheat yields from 15 experimental sites (one year) in a fictive agricultural region.
#' In this dataset, a study represents a site-year with 2 to 4 blocks.
#' Each block corresponds to an experimental plot on which the yield of the crop (expressed in t.ha-1) was measured.
#' Thus, each study contains 2 to 4 measurements of yields
