Abstract

Vine copula, constructed from bivariate copulas, provides great exibility in modelling complex high-dimensional dependence. When applied to multi- population mortality modelling, vine copula yields signi_cant improvement over traditional multivariate copulas. In this paper, we propose to capture time- varying features in mortality dependence with dynamic regular vine (R-vine) copula which is built from bivariate copulas with time-varying dependence pa- rameters. We develop two dependence dynamics for R-vine copulas and illustrate the selection and estimation of dynamic R-vine copulas using mortality data from eight populations. The estimated R-vine copulas using the proposed dependence dynam..
