PiklA: Matrix of inclusion probabilities for units selected in...
This dataset consists of a square matrix of dimension 105 with the first and second order inclusion probabilities
for the units included in sample s_A, which has been drawn from a population of size N_A = 1735 according to a
stratified random sampling with population strata sizes N_A^h = (727, 375, 113, 186, 115, 219)
#Let choose the submatrix of inclusion probabilities for the first 5 units sA.
#Now, let select only the first order inclusion probabilities
