Abstract: This paper describes a model-based estimation procedure for the variance of the generalized regression (GREG) estimator for the finite population totals. Two model-based estimators for the design variance of the GREG estimator are proposed. A simulation study is conducted to study the bias and efficiency of both estimators.

Keywords: GREG estimator, Model-based inference, Variance estimation.
