An efficient Hartley–Ross type estimators of nonsensitive and sensitive variables using robust regression methods in sample surveys
Zaman, Tolga; Shazad, Usman; Yadav, Vinay Kumar (Elsevier B.V., 2023)In sample surveys, the problem of outliers is one of the most frequent and widest, whose solution is required to be obtained using statistical techniques. To overcome this problem, various robust regression methods are ... -
Estimation of Population Mean Using Some Improved Imputation Methods for Missing Data in Sample Surveys
Pandey M.K.; Singh G.N.; Zaman, Togla (Taylor and Francis Ltd., 2024)Abstract.: In this research article, we present novel imputation methods designed to address missing data challenges in sample surveys. We then introduce innovative estimation procedures for calculating population means ... -
