#' Retinopathy
#'
#' The \code{retinopathy} data contains information on persons with retinopathy.
#'
#' @name retinopathy
#' @docType data
#' @format A data frame with 613 observations on the following 5 variables:
#' - RET: RET=1: no retinopathy, RET=2 nonproliferative retinopathy,
#' RET=3 advanced retinopathy or blind
#' - SM: SM=1: smoker, SM=0: non-smoker

#' Vasoconstriction and Breathing
#'
#' A binary data on the neural constriction of vasculature. Three test persons
#' inhaled a certain amount of air with different rates. In some cases a
#' vasoconstriction occurred at their skin. The objective of the study was to
#' indicate a correlation between breathing and vasoconstriction.
#' The test persons repeated the test 9, 8, 22 times, making a total of
#' 39 observations.
#'
#' @name vaso
#' @docType data
#' @format A data frame with 39 observations on the following 3 variables:
#' - vol: amount of air
#' - rate: rate of breathing
#' - vaso: condition of vasculature: no vasoconstriction = 1, vasoconstriction = 2

#'
#' - mode: recreation mode choice, one of : beach, pier, boat and charter,
#' - price.beach: price for beach mode
