Özet

This paper proposes some estimators for the population mean using the ratio estimators presented in [C. Kadilar, H. Cingi, Ratio estimators in simple random sampling, Applied Mathematics and Computation 151 (2004) 893-902] and shows that all proposed estimators are always more efficient than the ratio estimators. This result is also supported by a numerical example. (C) 2005 Elsevier Ltd. All rights reserved.
