DVineStructure

class DVineStructure

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__	Creates a new instance of the class.
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_json	Write the structure into a JSON file.
truncate	Truncates the R-vine structure.
