Estimating the Shannon Entropy of Several Exponential Populations

Suchandan Kayal, Somesh Kumar


The problem of estimating the Shannon’s entropy of several exponential populations using squared error as well as linex loss functions is considered when location parameters are known and scale parameters are unknown. Under the squared error loss function, the uniformly minimum variance unbiased estimator (UMVUE) is also a generalized Bayes estimator. We prove that it is admissible. A general inadmissibility result for the scale equivariant estimators is proved for both loss functions. Finally, under the linex loss function, a generalized Bayes estimator is shown to be admissible.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
