UPsystematicpi2 {sampling} | R Documentation |
Compute the joint inclusion probabilities for systematic sampling.
UPsystematicpi2(pik)
pik |
vector of first order inclusion probabilities. |
Return a NxN matrix with the first order inclusion probability for each unit k in the population on the first diagonal and with the joint inclusion probability of units k and l in position (k,l) in the matrix, where $kneq l$ (N is the population size).
