Estimation of finite population mean using two auxiliary variables under stratified random sampling

Yadav, Rohini; Tailor, Rajesh - In: Statistics in Transition New Series 21 (2020) 1, pp. 1-12

This paper addresses the problem of an alternative approach to estimating the population mean of the study variable with the help of the auxiliary variable under stratified random sampling. The properties of the suggested estimator have been studied under large sample approximation. It has been...
