 We consider the problem of estimation the population mean of the study variate Y in presence of measurement errors when information on an auxiliary character X is known. A class of estimators for population means using information on an auxiliary variate X is defined. Expressions for its asymptotic bias and mean square error are obtained. Optimum conditions are obtained for which the mean square errors of the proposed class of estimators are minimum.

 

Keywords: study variate, auxiliary variatc, measurement errors, bias, mean squared error.
