-    ----------
-    Marginals : obj

-
-    Examples
-    -------
-    Marginals can be defined as following:

-    >>> Inputs.Marginals[0].name = 'X_1'
-    >>> Inputs.Marginals[0].dist_type = 'uniform'
-    >>> Inputs.Marginals[0].parameters = [-5, 5]
-
-    If there is no common data is avaliable, the input data can be given
-    as following:
-
-    >>> Inputs.add_marginals()
-    >>> Inputs.Marginals[0].name = 'X_1'
