  1. Note: The parameters estimated by the model include θ and Dof, where θ is the correlation parameter and Dof is the degrees-of-freedom parameter. S.Clayton and S.Gumbel represent the survival Clayton and survival Gumbel copulas, respectively. *, **, and *** represent significance at 10%, 5%, and 1% levels, respectively.
