A ratio-cum-product estimator of population mean in stratified random sampling using two auxiliary variables
This paper proposes a ratio-cum-product estimator of finite population mean in stratified random sampling using information on population means of two auxiliary variables. The bias and mean squared error expressions are derived under large sample approximations. Proposed estimator has been compared...
