Asymptotic multivariate expectiles
Abstract
In [16], a new family of vector-valued risk measures called multivariate expectiles is introduced. In this paper, we focus on the asymptotic behavior of these measures in a multivariate regular variations context. For models with equivalent tails, we propose an estimator of these multivariate asymptotic expectiles, in the Fr\'echet attraction domain case, with asymptotic independence, or in the comonotonic case.
