#' Dependency of Anxiety on Stress
#'
#'For this data, stress and anxiety were measured among nonclinical women in Townsville, Queensland, Australia.
#'@usage data("StressAnxiety")
#'@details   Both variables were evaluated on the scales from 0 to 42, Smithson and Verkuilen (2006) transformed them in a range from 0 to 1.
#'@source Example 2 from Smithson and Verkuilen (2006) supplements.
#' @format   A data frame containing 166 observations on 2 variables.
#'\describe{
#'  \item{stress}{score, linearly transformed to the open unit
#'    interval (see below).}
#'  \item{anxiety}{score, linearly transformed to the open unit
#'    interval (see below).}
