A simulation study: Improved ratio-in-regression type variance estimator based on dual use of auxiliary variable under simple random sampling
In this article, we proposed an improved finite population variance estimator based on simple random sampling using dual auxiliary information. Mathematical expressions of the proposed and existing estimators are obtained up to the first order of approximation. Two real data sets are used to examine...
