摘要：
Some improved estimators of population mean has been proposed in two phase and multiphase sampling using information on two and several auxiliary variables. The minimum variance of the proposed estimators has been obtained. Comparison of the proposed estimators has been done with some available estimators of two phase sampling that utilizes information of two and several auxiliary variables.
