Exponential Methods of Estimation under Non-Response in Two-Occasion Rotation Patterns

G. N. Singh, M. Khetan, S. Maurya


The present work suggests exponential methods of estimation of current population mean in two occasion rotation patterns when non response occurs on first occasion. Using sub sampling of non-respondents technique, estimation procedure has been developed in presence of information on an auxiliary variable which is readily available on both occasions. Properties of the proposed estimation procedure have been examined and related optimum replacement strategy is suggested. Empirical study is carried out and results are interpreted to evaluate the performances of the proposed estimator. Suitable recommendations have been made.


Non-response, successive sampling, auxiliary information, bias, mean square error, optimum replacement strategy.
