Vine copulas are a flexible class of dependence models consisting of bivariate building blocks see e. You can find a comprehensive list of publications and other materials on vine-copula. This package is primarily made for the handbooj analysis of vine copula models. The package includes tools for parameter estimation, model selection, simulation, goodness-of-fit tests, and visualization. Tools for estimation, selection and exploratory data analysis of bivariate copula models are also provided.
Please see the API documentation for a detailed description of all functions. Below, we list most functions and features you should know about. As usual in copula models, data are assumed to be serially independent and lie in the unit hypercube. Returns an object of class BiCop. The class has the following methods:.
Dependence Modeling with Vine Copula – 人大经济论坛 – Powered by Discuz!
Possibly coupled with standard normal margins default for contour. Estimates parameters of a bivariate copula with a prespecified family. Estimates the parameters of a bivariate copula for a set of families and selects the best fitting model using either AIC or BIC. Vuong and Clarke tests for model comparison within a prespecified set of copula families. Conversion between dependence measures and parameters for a given family. Functions are vectorized in hadnbook arguments.
Evaluate functions related to a bivariate copula: Functions are handbpok in the familyparand par2 arguments. Further plot types for the analysis of bivariate copulas.
For most functions, you can provide an object of class BiCop instead of specifying familypar and par2 manually. Creates a vine copula model by specifying structure, family and parameter matrices. Such matrices have been introduced by Dissman et al. Returns an object of class RVineMatrix. Plots the trees of the the R-vine tree structure.
Optionally, you can annotate colula edges with pair-copula families and parameters. Estimates the parameters of a vine copula model with prespecified structure and families. Estimates the parameters and selects the best family for a vine copula model with prespecified structure matrix.
Fits a vine copula copulx assuming no prior knowledge. It selects the R-vine structure using Dissmann et al.
Goodness-of-Fit tests for a vine copula model c. Vuong and Clarke tests for comparing two vine copula models. Calculate dependence measures corresponding to a vine copula model. This is particularly useful for former users of the CDVine package.
Furthermore, bivariate and vine copula models from this packages can be used with the vinee package Hofert et al. For example, vineCopula transforms an RVineMatrix object into an object of class vineCopula which provides methods for dCopulapCopulaand rCopula. For more details, we refer to the package manual. In this package several bivariate copula families are included for bivariate and multivariate analysis using vine copulas.
For Archimedean copula mofeling, rotated versions are included to cover negative dependence as well. The Tawn copula is an asymmetric extension of the Gumbel copula with three parameters.

For copua, we implemented two versions of the Tawn copula with two parameters each. Each type has one of the asymmetry parameters fixed to 1, so that the corresponding copula density is modeljng left- or right-skewed in relation to the main diagonal. The following table shows the parameter ranges of bivariate copula families with parameters par and par2 and internal coding family:.
This small shiny app enables the user to draw nice tree plots of an R-Vine omdeling model using the package d3Network. Models have to be set up locally in an RVineMatrix object and uploaded as.
