Almost sure convergence of the stable tail empirical dependence function in multivariate extreme statistics

Acta Mathematicae Applicatae Sinica, 1997
Consider a bivariate i.i.d. sequence \((X_1Y_1)\), \((X_2,Y_2),\dots\) with joint d.f. \(F(x,y)\). Assume that \(F\) has a ``stable tail dependence function'' \(l(x,y)\), i.e. for \(x,y>0\), \[ l(x,y):= \lim_{t\downarrow 0} t^{-1} \{1-F(Q_1(tx), Q_2(ty))\} \] exists, where \(Q_i(x)= \sup\{y: 1-F_i(x)\geq x\}\), \(0\leq x\leq 1\) \((i=1,2)\).

Local estimation of the conditional stable tail dependence function [PDF]

open access: yes, 2017
We consider the local estimation of the stable tail dependence function when a random covariate is observed together with the variables of main interest.

A continuous updating weighted least squares estimator of tail dependence in high dimensions [PDF]

open access: yesExtremes, 2017
Likelihood-based procedures are a common way to estimate tail depen- dence parameters. They are not applicable, however, in non-differentiable models such as those arising from recent max-linear structural equation models.
