摘要

极值指数(EVI)的估计是极值统计领域的一项重要任务,因为它能为了解分布的尾部行为提供有价值的信息。对于帕累托类型的尾部模型,希尔估计器是一种常用的选择。然而,这种估计器容易出现偏差,导致对经济脆弱性指数的估计不准确,影响风险评估和决策过程的可靠性。本文介绍了一种新颖的减少偏差的广义希尔估计器,旨在通过减少偏差来提高经济脆弱性指数估计的准确性。

A New Class of Reduced-Bias Generalized Hill Estimators
The estimation of the extreme value index (EVI) is a crucial task in the field of statistics of extremes, as it provides valuable insights into the tail behavior of a distribution. For models with a Pareto-type tail, the Hill estimator is a popular choice. However, this estimator is susceptible to bias, which can lead to inaccurate estimations of the EVI, impacting the reliability of risk assessments and decision-making processes. This paper introduces a novel reduced-bias generalized Hill estimator, which aims to enhance the accuracy of EVI estimation by mitigating the bias.
