jipApprox: Approximate inclusion probabilities for survey sampling

Function `jip_approx`

provides a number of approximations of the
second-order inclusion probabilities that require only the first-order inclusion
probabilities. These approximations may be employed in unequal probability sampling
design with high entropy. A more flexible approximation may be obtained by using
function `jip_MonteCarlo`

, which estimates inclusion probabilities
through a Monte Carlo simulation.

The variance of the Horvitz-Thompson total estimator may be then estimated by
plugging the approximated joint probabilities into the Horvitz-Thompson or
Sen-Yates-Grundy variance estimator using function `HTvar`

.
