An Alternative Class of Exponential Type Estimator in Simple Random Sampling

J. O. Uket, E. I. Enang, I. N. Ikpang


This paper provides an alternative class of exponential type estimator for population mean in SRSWOR. The mean square error (MSE) as well as the bias of the proposed alternative class of estimator is obtained. Comparison of the class is done using analytical and numerical illustrations and from results obtained, it is observed that members of the proposed alternative class of estimators are more efficient than some existing estimators.
