Local Gaussian copula inference with structural breaks: testing dependence predictability

Alexander Mayer, Tatsushi Oka, Dominik Wied

We propose a score test for dependence predictability in conditional copulas that is robust to temporal instabilities. Our semiparametric procedure accommodates flexible dynamics i…
