ABSTRACT The GPD is a central distribution in modelling heavy tails in many applications. Applying the GPD to actual datasets however is not trivial. In this paper we propose the Exponentiated GPD (exGPD), created via log-transform of the GPD variable, which has less sample variability. Various distributional quantities of the exGPD are derived analytically. As an application we also propose a new plot based on the exGPD as an alternative to the Hill plot to identify the tail index of heavy… Expand

Estimating extreme tail risk measures with generalized Pareto distribution
A new GPD parameter estimator is proposed, based on a nonlinear weighted least squares method, to estimate common tail risk measures, the Value-at-Risk (VaR) and Conditional Tail Expectation (also known as Tail- VaR) for heavy-tailed losses. Expand
A quantile estimation for massive data with generalized Pareto distribution
The parameter estimation method has a smaller Mean square error (MSE) than other common methods when the shape parameter of GPD is at least 0.5 and shows the best performance in terms of root MSE (RMSE) and absolute relative bias (ARB) for heavy-tailed distributions. Expand
Fitting the Generalized Pareto Distribution to Data
Abstract The generalized Pareto distribution (GPD) was introduced by Pickands to model exceedances over a threshold. It has since been used by many authors to model data in several fields. The GPDExpand

This work considers the method of medians estimator for the two-parameter Weibull model, which has a bounded influence function and is highly robust against outliers, easy to compute as it requires solving only one equation instead of a pair of equations as for most M-estimators. Expand
