#' @title Randomized Response Survey on infidelity
#' 
#' @description This data set contains observations from a randomized response survey conducted in a university to investigate the infidelity.
#' The sample is drawn by stratified (by faculty) cluster (by group) sampling.
#' The randomized response technique used is the Horvitz model (Horvitz et al., 1967 and Greenberg et al., 1969) with parameter \eqn{p=0.6}.
#' The unrelated question is: Does your identity card end in an odd number? with a probability \eqn{\alpha=0.5}.
#' 
#' @format
#' A data frame containing 365 observations from a population of \eqn{N=1500} students divided into two strata. The first strata has 14 cluster and the second has 11 cluster.
#' The variables are:
#' \itemize{
#'     \item ID: Survey ID of student respondent
#'     \item ST: Strata ID
#'     \item CL: Cluster ID
#'     \item z: The randomized response to the question: Have you ever been unfaithful?   
#'     \item Pi: first-order inclusion probabilities
