Ahmed Audu, Mojeed Abiodun Yunusa, Aminu Bello Zoramawa, Samaila Buda & Ran Vijay Kumar Singh · Asian Journal of Probability and Statistics · 2021

Human-assisted surveys, such as medical and social science surveys, are frequently plagued by non-response or missing observations. Several authors have devised different imputation algorithms to account for missing observations during analyses. Nonetheless, several of these impu...

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...
