The kdevine package is no longer actively developed.Consider using - the kde1d package for marginal estimation, - the functions`vine()`

and`vinecop()`

from the rvinecopulib package as replacements for`kdevine()`

and`kdevincop()`

.

This package implements a vine copula based kernel density estimator. The estimator does not suffer from the curse of dimensionality and is therefore well suited for high-dimensional applications (see, Nagler and Czado, 2016). The package is built on top of the copula density estimators in kdecopula and let’s you choose from all its implemented methods. The package can handle discrete and categorical data via continuous convolution.
