StratifiedSampling (version 0.4.1)

maxentpi2: 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)

Value

A matrix, the joint inclusion probabilities.

Arguments

pikr

A vector of inclusion probabilities.

Author

Raphaël Jauslin

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).
