(Mean-Variance, Archimedean).

Mean-Variance Copulas
---------------------

Copulas derived from normal mixture distributions (McNeil, Frey,
Embrechts 2005, §3.2).  ``MeanVarianceCopulaBase`` is the umbrella;
:class:`EllipticalCopula` covers normal *variance* mixtures
(Gaussian, Student-T; γ=0, strictly elliptical); :class:`MeanVarianceCopula`
covers normal *mean-variance* mixtures (GH, Skewed-T; γ≠0).

Archimedean Copulas
-------------------

Copulas defined by a generator function φ and its inverse ψ.
