Stress Testing German Industry Sectors: Results from a Vine Copula Based Quantile Regression
, 2017 Measuring interdependence between probabilities of default (PDs) in different industry sectors of an economy plays a crucial role in financial stress testing. Thereby, regression approaches may be employed to model the impact of stressed industry sectors

Operational Convection‐Permitting COSMO/ICON Ensemble Predictions at Observation Sites (CIENS)
Geoscience Data Journal, Volume 13, Issue 1, January 2026.Map of synoptic stations in Germany for which ensemble forecasts and observations are provided in the CIENS dataset. Colours represent the station altitude in metres. ABSTRACT We present the CIENS dataset, which contains ensemble weather forecasts from the operational convection‐permitting numerical weather prediction model of the German Weather ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015 The article points out the possibilities of using static D-Vine copula ARMA-GARCH model for estimation of 1 day ahead market Value at Risk. For the illustration we use data of the four companies listed on Prague Stock Exchange in range from 2010 to 2014.

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This study develops a spatiotemporal source‐load scenario generation framework using Copula‐Markov chains, R‐Vine Copulas and user behaviour models. A novel flexibility assessment framework quantifies supply‐demand imbalances, showing flexibility resources like demand response and VSC capacity shape system flexibility. ABSTRACT Global energy transition

Testing the simplifying assumption in high-dimensional vine copulas
, 2021 Testing the simplifying assumption in high-dimensional vine copulas is a difficult task. Tests must be based on estimated observations and amount to checking constraints on high-dimensional distributions.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.This paper proposes a scenario generation method for wind/photovoltaic power outputs and load sequences, which is able to preserve the characteristics of extreme scenarios. The method extracts extreme scenarios via an iterative procedure and generates conventional scenarios using a double‐layer Markov chain Monte Carlo model.

Variational Bayes Estimation of Discrete-Margined Copula Models with Application to Time Series
, 2018 We propose a new variational Bayes estimator for high-dimensional copulas with discrete, or a combination of discrete and continuous, margins. The method is based on a variational approximation to a tractable augmented posterior, and is faster than ...
