Predictive estimation of finite population mean using product estimator
- 53 Downloads
If the predictive approach advocated byBasu  is adopted for estimating the mean of a finite population, it is observed that the use of mean per unit estimator, regression estimator and ratio estimator as a predictor for the mean of unobserved units in the population result in the corresponding customary estimators of the mean of the whole population. Whereas if the product estimator is used as a predictor for the mean of unobserved units in the population, the resulting estimator of the mean of the whole population is different from the customary product estimator. The new estimator so obtained is compared with the customary product estimator.
