The Peaks over Thresholds Method for Estimating High Quantiles of Loss Distributions
نویسندگان
چکیده
We review the peaks over thresholds or POT method for modelling tails of loss severity distributions and discuss the use of this technique for estimating high quantiles and the possible relevance of this to excess of loss insurance in high layers. We test the method on a variety of simulated heavy-tailed distributions to show what kind of thresholds are required and what sample sizes are necessary to give accurate estimates of quantiles.

Estimating the Extreme Value Index and High Quantiles with Exponential Regression Models
In this paper we present exponential regression models for spacings, or ordered excesses over a given threshold, and for log-ratios of such spacings under maximum domain of attraction conditions. From these we derive estimators for the extreme value index (EVI) and for high quantiles, which share many attractive properties of the maximum likelihood estimators from the peaks-over-thresholds meth...
متن کاملQuantile Estimation for the Generalized Pareto Distribution with Application to Finance
Generalized Pareto distributions (GPD) are widely used for modeling excesses over high thresholds (within the framework of the POT-approach to modeling extremes). The aim of the paper is to give the review of the classical techniques for estimating GPD quantiles, and to apply these methods in finance to estimate the Valueat-Risk (VaR) parameter, and discuss certain difficulties related to this ...
متن کاملHigh quantile regression for extreme events
For extreme events, estimation of high conditional quantiles for heavy tailed distributions is an important problem. Quantile regression is a useful method in this field with many applications. Quantile regression uses an L1-loss function, and an optimal solution by means of linear programming. In this paper, we propose a weighted quantile regression method. Monte Carlo simulations are performe...
متن کاملEstimating high quantiles for electricity prices by stable linear models
We estimate conditional and unconditional high quantiles for electricity spot prices based on a linear model with stable innovations. This approach captures the impressive peaks in such data and, as a four-parametric family captures also the assymmetry in the innovations. Moreover, it allows for explicit formulas of quantiles, which can then be calculated recursively from day to day. We also pr...

Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...
