چکیده
In the present work, some efforts have been made to search of effective rotation patterns in estimation of precision of population mean of study variable on current occasion in two-occasion successive sampling. Information on an auxiliary character, which is readily available on previous and current occasion, has been used along with the information on study character from the first and second occasion. Exponential ratio and regression type estimators have been proposed, and their behaviors are examined. Optimum replacement strategy relevant to the proposed estimation procedure has been discussed. Theoretical and empirical results have been interpreted to justify the efficiency of the proposed estimators. Proposed estimators have been compared with natural estimators and suitable recommendations have been made.
