DVineStructure

class DVineStructure(*args, **kwargs)

A class for D-vine structures.

D-vines are a special class of R-vines where each tree is a path. A D-vine structure is determined entirely by the order of variables. For example, if the order is (1, 2, 3, 4), the first tree in the vine is 1-2-3-4 and all further trees are unique due to the proximity condition.

Note that DVineStructure objects inherit the methods and attributes of RVineStructure objects.

Attributes

dim	The dimension.
matrix	Gets the R-vine matrix representation.
order	The variable order.
trunc_lvl	The truncation level.

Methods

__init__
from_dimension	Instantiates as a D-vine for a given dimension.
from_file	Instantiates an RVineStructure from a JSON file.
from_json	Instantiates from a JSON-like str object.
from_matrix	Instantiates an RVineStructure object from a matrix representing an R-vine array.
from_order	Instantiates as a D-vine with a given ordering of the variables.
min_array	Access elements of the minimum array.
needed_hfunc1	Access elements of the needed_hfunc1 array.
needed_hfunc2	Access elements of the needed_hfunc2 array.
simulate	Randomly sample a regular vine structure.
str	Converts the structure to a string representation (most useful for printing).
struct_array	Accesses elements of the structure array.
to_file	Write the structure into a JSON file.
to_json	Converts the structure into a JSON-like str object.
truncate	Truncates the R-vine structure.
