Bicop.__init__

Bicop.__init__(self, family: pyvinecopulib.BicopFamily = BicopFamily.indep, rotation: int = 0, parameters: numpy.ndarray[dtype=float64, shape=(*, *)] = array([], shape=(0, 0), dtype=float64), var_types: collections.abc.Sequence[str] = ['c', 'c']) → None

Default constructor for the Bicop class.

The default constructor uses Bicop.from_family() to instantiate an independent bivariate copula. It can then be used to select a model from data using Bicop.select(). Or if a BicopFamily is passed to the constructor, then the method Bicop.fit() can be used to fit the copula to data.

Alternatives to instantiate bivariate copulas are:

• Bicop.from_family(): Instantiate from a family, rotation, parameters, and variable types.

• Bicop.from_data(): Instantiate from data, as well as optional controls and variable types.

• Bicop.from_file(): Instantiate from a file.

• Bicop.from_json(): Instantiate from a JSON string.
