Abstract:This paper proposed a new predictor based on the generalized Liu estimator in finite populations.The necessary and sufficient conditions for the superiority of the predictor based on the generalized Liu estimator over the best linear unbiased predictor in the prediction mean squared error sense were derived.Furthermore,a numerical example was given to illustrate some of the theoretical results.
Keywords:finite populations  prediction mean squared error  best linear unbiased predictor  generalized Liu estimator
