摘要：

In the present study, we propose two new estimators for population mean using Kadilar and Cingi (2005) [2] and Lu et al. (2010) [9] estimators in the case when the information is available in form of attributes. Expressions for the MSE's of the proposed estimator are derived up to the first degree of approximation. The theoretical conditions have also been verified by a numerical example. It has been shown that the proposed estimators are more efficient than usual regression estimators. (C) 2013 Elsevier Inc.
