#' Kernel Smoothing for Bivariate Copula Densities
#'
#' 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 multivariate kernel density estimators is implemented by the
#' \code{\link{kdevine}} function. It combines a kernel density estimator for
#' the margins (\code{\link{kde1d}}) and a kernel estimator of the vine copula
#' density (\code{\link{kdevinecop}}). The package is built on top of the copula
#' density estimators in the [kdecopula::kdecopula-package] and let's you
#' choose from all its implemented methods. Optionally, the vine copula can be
#' estimated parameterically (only the margins are nonparametric).
