La méthode POT (pics au-delà d'un seuil) consiste à utiliser une distribution de Pareto généralisée (GPD) pour approximer la loi des excès au-delà d'un seuil. Dans cette Note, nous proposons des estimateurs de quantiles extrêmes basés sur cette méthode. Nous établissons leurs normalités asymptotiques sous des hypothèses générales.
The POT (Peaks-Over-Threshold) approach consists in using the generalized Pareto distribution (GPD) to approximate the distribution of excesses over thresholds. In this Note, we propose extreme quantile estimators based on this method. We establish their asymptotic normality under suitable general assumptions.
