maxentpi2 {StratifiedSampling} | R Documentation |
Joint inclusion probabilities of maximum entropy.
Description
This function computes the matrix of the joint inclusion of the maximum entropy sampling with fixed sample size. It can handle unequal inclusion probabilities.
Usage
maxentpi2(pikr)
Arguments
pikr |
A vector of inclusion probabilities. |
Details
The sampling design maximizes the entropy design:
I(p) = - \sum s p(s) log[p(s)].
This function is a C++ implementation of UPMEpik2frompikw
.
More details could be find in Tille (2006).
Value
A matrix, the joint inclusion probabilities.
