Developing calibration estimators for population mean using robust measures of dispersion under stratified random sampling

Audu, Ahmed; Singh, Rajesh; Khare, Supriya - In: Statistics in Transition New Series 22 (2021) 2, pp. 125-142

In this paper, two modified, design-based calibration ratio-type estimators are presented. The suggested estimators were developed under stratified random sampling using information on an auxiliary variable in the form of robust statistical measures, including Gini's mean difference, Downton's...
