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](https://github.com/tnagler/kdecopula) and let’s you choose from all its implemented methods. The package can handle discrete and categorical data via [continuous convolution](https://github.com/tnagler/cctools). - [How to install](#how-to-install) - [Functionality](#functionality) - [References](#references) ----- ## How to install You can install: - the stable release on CRAN: <!-- end list --> ``` r install.packages("kdevine") ``` - the latest development version: <!-- end list --> ``` r devtools::install_github("tnagler/kdevine") ``` ## Functionality A detailed description of of all functions and options can be found in the [API documentaion](https://tnagler.github.io/kdevine/reference/index.html). In short, the package provides the following functionality: - Class `kdevine` and its methods: - `kdevine()`: Multivariate kernel density estimation based on vine copulas. Implements the estimator of (see, Nagler and Czado, 2016). - `dkdevine()`, `rkdevine()`: Density and simulation functions. - Class `kdevinecop` and its methods: - `kdevinecop()`: Kernel estimator for the vine copula density (see, Nagler and Czado, 2016). - `dkdevinecop()`, `rkdevinecop()`: Density and simulation functions. - `contour.kdevinecop()`: Matrix of contour plots of all pair-copulas. - Class `kde1d` and its methods: - `kde1d()`: Univariate kernel density estimation for bounded and unbounded support. - `dke1d()`, `pkde1d()`, `rkde1d()`: Density, cdf, and simulation functions. - `plot.kde1d()`, `lines.kde1d()`: Plots the estimated density. ## References Nagler, T., Czado, C.
