UPmidzunopi2 {sampling} | R Documentation |
Compute the joint inclusion probabilities for Midzuno sampling.
UPmidzunopi2(pik)
pik |
vector of 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 k and l are not equal (N is the population size).
