Such estimation can be more robust than inference tied to model based inference. A nonparametric procedure for estimating error variance is suggested. An empirical example is given to illustrate the performance of the derived estimator vis-a-vis the currently popular variance estimator in model based surveys.enAuxiliary variablebandwidthkernel estimatorratio estimatornon-parametric regressionvariance estimationArticle
