Vinecop

class Vinecop

A class for vine copula models.

A vine copula model is characterized by its structure (see RVineStructure objects) and the pair-copulas.

Attributes

dim	The dimension.
families	Families of all pair-copulas.
matrix	The R-vine structure’s matrix.
nobs	The number of observations (for fitted objects only).
npars	The total number of parameters.
order	The R-vine structure’s order.
pair_copulas	All pair-copulas.
parameters	The parameters of all pair-copulas.
rotations	The rotations of all pair-copulas.
structure	The R-vine structure.
taus	The Kendall’s taus of all pair-copulas.
threshold	The threshold (for thresholded copulas only).
trunc_lvl	The truncation level.
var_types	The types of each variables.

Methods
