Abstract

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