#' @title Randomized Response Survey on spending on alcohol
#' 
#' @description This data set contains observations from a randomized response survey conducted in a population of students to investigate spending on alcohol.
#' The sample is drawn by simple random sampling with replacement.
#' The randomized response technique used is the Saha model (Saha, 2007) with scramble variables \eqn{W=U(1,2)} and \eqn{U=U(1,10)}.
#' 
#' @format A data frame containing 100 observations. 
#' The variables are:
#' \itemize{
#'  \item ID: Survey ID
