On unbiased estimation of the tail Pareto index based on k-record values

Mohamed El ARROUCHI, Abdelouahid IMLAHI


In this paper, and in a context of regularly varying tails, we propose an unbiased estimator for the tail Pareto index of a distribution based on kn-record values observed in a sample (X1; :::;Xn) and show its asymptotic properties. Some simulations are also provided to validate the theoretical results.

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.
