PiklA: 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 $s_A$, which has been drawn from a population of size $N_A = 1735$ according to a
stratified random sampling with population strata sizes $N_A^h = (727, 375, 113, 186, 115, 219)$
