dc.description.abstractIn this paper, robustness of suggested modified factor-type estimators have been study under non-response model in relation to other existing related estimators of population mean. Mean square error (MSE) of suggested estimators under non-response model has been obtained and empirical study was done using Data 1, 2, 3 and 4. The robustness of the considered estimators were obtained by averaging their expected MSE and ranked accordingly to their level of efficiency. The results revealed that the efficiency of all the estimators considered increases as the proportion of non-respondent who responded after been re-interviewed increases and the suggested estimators compete favorably with almost the estimators considered in the studyen_US
