var_Brewer_class3 {UPSvarApprox} | R Documentation |
Approximate Variance Estimators by Brewer (2002)
Description
Compute an approximate variance estimate using the class of estimators proposed by Brewer (2002). Estimators of class 3, they require only first-order inclusion probabilities but for all population units.
Usage
