A Class of Product-Type Estimator when there is Unit Non-Response in the Study Variable
Keywords:
Product type, Estimator, Variable, Non-response, bias, Mean square errorAbstract
We have proposed a class of product-type estimator for the estimation of the population mean when there is unit nonresponse. We are able to show, under a given model, that our estimator is more eficient than the sample mean given by Hansen and Hunvitz (1946). We also established theoretically the condition under which our estimator is more efficient than other particular estimators derivable from the given class of estbnators. It has also been shown that it is better to adjust the auxiliary variablefor non-response even when there is convlete response in the auxiliary variable.
