The aim of this note is to prove the equivalence between the class of conic copulas and the class of Archimax copulas based on the lower Frechet–Hoeffding bound  W . We demonstrate the transition from arbitrary conic copula to appropriate Pickands dependence function, and vice-versa. Our results show that Archimax copulas are isomorphic transforms of either  EV -copulas or conic copulas.
