摘要 当极值指标小于0时,该文提出了一种负极值指标估计量,证明了该估计量的弱相合性和强相合性;在二阶正规变化条件下,通过限制正规变化函数的收敛速度,给出了强收敛速度和渐近展式,证明了渐近正态性,并对平滑参数的最优选择进行了讨论. As the extreme-value index is negative,the author proposes the negative extremevalue index estimator,whose weak and strong consistency are proved.Under the second order regularly varying condition,the author obtains the rate of strong convergence,asymptotic expansion and proves asymptotic normality.Moreover,the optimal choice of the smoothing parameter is discussed.
