A GENERAL FAMILY OF RATIO-TYPE ESTIMATORS IN SYSTEMATIC SAMPLING

In this paper, we have adapted Gupta and Shabbir (2008) estimator in systematicsampling using auxiliary information. For the family of estimators, under systematic sampling theexpression of mean square error (MSE) up to the first order approximations is derived. Thefamily of estimators in its optimum case is discussed. Also, an empirical study is carried out toshow the properties of the proposed estimators.
