parameterssample designunbiased estimatorsadmissibilityA general sufficient condition is found for estimators of a finite population parameter to be admissible in the class of its unbiased estimators. The solution extends a result given by Godambe and Joshi and appears as a unified condition which ...
Use Rao - Blackwell to find UMVUE for the Unbiased Estimator of \Theta e^{-\Theta} Let X_1 X_2,...Xn , denote a random sample from a population having a mean mu and variance sigma^2 . a. Which one of the following estimators of mu it the best? (Justify your answer) theta Sho...
In this paper, we have proposed three classes of almost unbiased estimators for population mean under simultaneous presence of measurement and non-response error. Asymptotic properties such as Bias and MSE for the proposed classes of estimators are obtained. Numerical illustration in support of ...
Estimators are only approximations and cannot perfectly approximate population parameters. The term bias refers to the difference between the estimated value and the actual population value. In other words, the statistic is a biased estimator if it overestimates or underestimates the population parameter...
