Define a joint distribution from a list of marginals and a copula to introduce dependency. :class:`.JointCopula` is a child class of :class:`.DistributionND`.
A :class:`.JointCopula` distribution may possess a :py:meth:`cdf`, :py:meth:`pdf` and :py:meth:`log_pdf` methods if the copula allows for it (i.e., if the copula possesses the necessary :meth:`evaluate_cdf` and :meth:`evaluate_pdf` methods - See :class:`.Copula`).
The parameters of the distribution are only stored as attributes of the marginals/copula objects. However, the
:meth:`get_parameters` and :meth:`update_parameters` methods can still be used for the joint. Note that each parameter of
the joint is assigned a unique string identifier as key_index - where key is the parameter name and index the
index of the marginal (e.g., location parameter of the 2nd marginal is identified as loc_1); and key_c for
copula parameters.
The :class:`.JointCopula` class is imported using the following command:
>>> from UQpy.distributions.collection.JointCopula import JointCopula.. autoclass:: UQpy.distributions.collection.JointCopula
