Generalized Estimators for Finite Population Variance Using Measurable and Affordable Auxiliary Character

Isah Muhammad, Yahaya Zakari & Ahmed Audu · Asian Research Journal of Mathematics · 2022

In this paper, a generalized exponential-type estimator for estimating the population variance using measurable and affordable auxiliary character in single phase sampling has been proposed. Some special cases of the proposed generalized estimator with a = 1 and a = 2 have also b...
