NAYAK, RADHAKANTA e SAHOO, LOKANATH. Some Alternative Predictive Estimators of PopulationVariance. Rev.Colomb.Estad. [online]. 2012, vol.35, n.3, pp.509-521. ISSN 0120-1751.
Using a predictive estimation procedure, an attempt has been made to develop some estimators for the finite population variance in the presence of an auxiliary variable. Analytical and simulation studies have been undertaken for understanding the performance of the suggested estimators compared to some existing ones.
