#' Mesquite data set
#'
#' The mesquite bushes yields dataset from Gelman and Hill (2006)
#' (<https://sites.stat.columbia.edu/gelman/arm/>).
#'
#' @format The response variable is the total weight (in grams) of
#'   photosynthetic material as derived from actual harvesting of the bush. The
#'   predictor variables are:
#' \describe{
#'   \item{diam1}{diameter of the canopy (the leafy area of the bush) in meters,
#'   measured along the longer axis of the bush.}
#'   \item{diam2}{canopy diameter measured along the shorter axis.}
#'   \item{canopy height}{height of the canopy.}
#'   \item{total height}{total height of the bush.}
#'   \item{density}{plant unit density (# of primary stems per plant unit).}
#'   \item{group}{group of measurements (0 for the first group, 1 for the second
#'   group).}
