#' @title Matrix of inclusion probabilities for units selected in sample from frame A
#' 
#' @description This dataset consists of a square matrix of dimension 105 with the first and second order inclusion probabilities
#'  for the units included in sample \eqn{s_A}, which has been drawn from a population of size \eqn{N_A = 1735} according to a
#'  stratified random sampling with population strata sizes \eqn{N_A^h = (727, 375, 113, 186, 115, 219)}
