摘要:
In this paper, a new class of location-invariant semi-parametric estimators of a positive extreme value index gamma>0 is proposed. Its asymptotic distributional representation and asymptotic normality are derived, and the optimal choice of the sample fraction by mean squared error is also discussed for some special cases. Finally comparison studies are provided for some familiar models by Monte Carlo simulations.
