Web1 de fev. de 2024 · In this paper, we introduce a hierarchical copula that allows to have a block exchangeability structure, in which within-block copulas are Archimedean and between-block copulas are non-exchangeable (in particular pairs that belong to different blocks are asymmetric). WebArchimedean copula has been widely studied in empirical finance (e.g. Savu & Trede, 2008; Gaiduchevici, 2014). Wang et al. (2015) applied a four-dimensional version (with Gumbel-Hougaard, Clayton copulas) to the mortality indices of four countries. It is relatively easy to use and is parsimonious in terms of having only one parameter.
