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.
