Semiparametric Estimation and Panel Data Clustering Analysis Based on D-Vine and C-Vine

Table 1

The comparison of three ways of copula construction.

copula	Number of copulas, self-defined	Parameter constraint	Copula family
EAC	1	No	Archimedes copula
HNAC	d-1		Archimedes copula
PCC	d(d-1)/2	No	Any copula

Here HNAC is a representative of NAC.
Here d represents the number of dimensions of the copula.
