Improved Generalized Chain Estimators for Ratio and Product of Two Population Means Using Two Auxiliary Characters in the Presence of Non-Response

B. B. Khare, P. S. Jha, Kamlesh Kumar


Two improved generalized chain estimators for ratio and product of two population means using two auxiliary characters in the presence of non-response have been proposed and their properties are studied. A comparative study is also made with the relevant estimators and the empirical study shows the efficiency of the proposed estimators for ratio and product of two population means with relevant estimators.


Double sampling; Non-response; Mean square error; Relative bias; Auxiliary characters.
