主 题:Tail index Parameter estimation,Strong convergence Mean squared error Comparisons of estimators
摘 要:The author obtains the rate of strong convergence,mean squared error and optimal choice of the“smoothing parameter(the sample fraction)of a tail index estimator which was proposed by the author from Pickands’estimator,and called modified Pickands’*** similar results about Hill’s estimator are also obtained,which generalize the corresponding results ***,some comparisons between Hill’s estimator and the modified Pickands’estimator are given.
