New Ratio Estimators of a Population Mean Using One Auxiliary Variable in Simple Random Sampling
The new ratio estimators of a population mean using one auxiliary variable in simple random sampling are introduced. The efficiency of these estimators are compared with the ratio estimators proposed by Sisodia and Dwivedi (1981), Singh and Kakran (1993) and, Upadhyaya and Singh (1999) on the basis...
