ESTIMATION OF POPULATION PROPORTION USING AUXILIARY CHARACTER IN THE PRESENCE OF NONRESPONSE
Two classes of estimators for population proportion using auxiliary character with known population mean in the presence of non-response on the study character have been proposed. Some members of the proposed classes of estimators are given. The expressions for bias and mean square error of the proposed classes of estimators are obtained in case of fixed sample size. The performance of the proposed classes of estimators with the relevant estimator is supported with the help of an empirical study.
