ABSTRACT

Two classes of estimators for the population mean of the study character using multi-auxiliary characters with known population means in presence of nonresponse have been proposed. The expressions for bias, mean square error and conditions for attaining minimum mean square error of the proposed classes of estimators have been obtained. An empirical study has also been given in support of the problem.

KEYWORDS
