Optimality of ratio and regression type estimators using dual of auxiliary variable under non response
The present note addresses the problem of estimation of population mean in the presence of non response. We have proposed the difference and ratio type estimators in two distinct situations of non response using the dual of an auxiliary variable. Some conventional estimators like mean, ratio, produc...
