Estimation of population mean using multivariate stratified sampling: an analysis of child mortality and parental education

Accurate estimation of population means is an important objective in survey sampling, as it provides reliable information for decision-making and policy formulation. To improve estimation efficiency, this study proposes a new estimator for the population mean in stratified random sampling by incorporating two auxilia...

A robust population mean estimation method in stratified sampling using auxiliary attributes under real and simulated populations

This study proposes a novel improved ratio-type estimator for efficient estimation of the population mean in stratified sampling by integrating auxiliary attribute information through a unified nonlinear framework. Unlike conventional ratio, product, and exponential-type estimators, the proposed estimator combines thes...
