摘要：
For the estimation of population mean, a generalized class of estimators using known coefficient of variation C-y of the study variable y is proposed, its bias and mean square error (MSE) are found and its comparative study with the usual mean per unit estimator has been done. As an illustration, an empirical study is also included. Copyright (C) 1997 Elsevier Science Ltd.
