Nettet25. mai 2024 · We find that the upper tail behaviour of the aggregate is driven by different factors dependent on the signs of the marginal shape parameters; if they are both negative, the extremal behaviour of the aggregate is determined by both marginal shape parameters and the coefficient of asymptotic independence (Ledford and Tawn, … Nettet25. mai 2024 · The extremal behaviour of the marginal variables is characterised by the generalised Pareto distribution and their extremal dependence is characterised using …

NettetIn this paper, we follow the approach introduced by Ledford and Tawn (1996) and extended by Ramos and Ledford (2009). Before explaining the details of our method, we need to recall a few basic concepts about MEVT and to intro-duce some notations.
