Elliptical copulas: applicability and limitations
G Frahm, M Junker, A Szimayer - Statistics & Probability Letters, 2003 - Elsevier
We study copulas generated by elliptical distributions. We show that their tail dependence
can be simply computed with default routines on Student's t-distribution given Kendall's τ and …
