RATIO AND RATIO TYPE SEPARATE ESTIMATOR FOR POPULATION MEAN WHEN COEFFICIENT OF VARIATION IS KNOWN
Keywords:
Population Mean, Sample Mean, Stratification, Separate Type Estimator, Separate Ratio and Ratio Type EstimatorAbstract
This paper deals with the problem of estimation of the finite population mean using auxiliary information. A ratio and ratio type separate estimator has been suggested for the finite population mean. The bias and mean squared error have been derived. The suggested estimator has been compared theoretically as well as empirically with existing estimators.
