UPSvarApprox: Approximate the variance of the Horvitz-Thompson estimator

Description

Variance approximations for the Horvitz-Thompson total estimator in Unequal Probability Sampling using only first-order inclusion probabilities. See Matei and Tillé (2005) and Haziza, Mecatti and Rao (2008) for details.

Variance approximation

The package provides function Var_approx for the approximation of the Horvitz-Thompson variance, and function approx_var_est for the computation of approximate variance estimators. For both functions, different estimators are implemented, see their documentation for details.
