Dual Transformation of Auxiliary Variables by Using Outliers in Stratified Random Sampling

open access: yesMathematics
To estimate the finite population variance of the study variable, this paper proposes an improved class of efficient estimators using different transformations. When both the minimum and maximum values of the auxiliary variable are known and the ranks of

Optimizing Finite Population Mean Estimation Using Simulation and Empirical Data

open access: yesMathematics
Two-phase sampling is an effective sampling approach that is useful in sample surveys when prior auxiliary information is not available. When two variables have an association, the ranks of the auxiliary variable are proportional to the study variable ...
