Vinecop.to_json

Vinecop.to_json(self) → str

Converts the copula into a nlohmann::json object.

The JSON-like str object contains two nodes : "structure" for the vine structure, which itself contains nodes "array" for the structure triangular array and "order" for the order vector, and "pair copulas". The former two encode the R-Vine structure and the latter is a list of child nodes for the trees ("tree1", "tree2", etc), each containing a list of child nodes for the edges ("pc1", "pc2", etc). See Bicop::to_json() for the encoding of pair-copulas.

Returns:

the nlohmann::json object containing the copula.
