Available constructor:
    FarlieGumbelMorgensternCopulaFactory()

We note :math:`\Hat{\tau}_n` the Kendall-\ :math:`\tau` of the sample
and :math:`\Hat{\rho}_n` its Spearman correlation coefficient.

We use the following estimators:

.. math::

    \Hat{\theta}_n = \displaystyle \frac{9}{2}\Hat{\tau}_n^{\strut}` 

if :math:`|\Hat{\theta}_n|<1`.

Otherwise

.. math::

    \Hat{\theta}_n = \displaystyle 3\Hat{\rho}_n^{\strut}`

if :math:`|\Hat{\theta}_n|<1`.

Otherwise, the estimation is not possible.
