rcpptimer: Rcpp Tic-Toc Timer with OpenMP Support
We developed ‘cpptimer’, a straightforward tic-toc timer class for benchmarking C++ code to address this. Unlike existing solutions, ‘cpptimer’ supports overlapping timers and OpenMP parallelism. It also calculates summary statistics when benchmarking the same code segment multiple times. Being a header-only library, ‘cpptimer’ is easily bindable to higher-level languages.

Online Distributional Regression, 2024, Simon Hirsch, Jonathan Berrisch, Florian Ziel
We present a methodology for online estimation of regularized, linear distributional models. The proposed algorithm is based on a combination of recent developments for the online estimation of LASSO models and the well-known GAMLSS framework. We provide a case study on day-ahead electricity price forecasting, in which we show the competitive performance of the incremental estimation combined with strongly reduced computational effort. Our algorithms are implemented in a computationally efficient Python package.

Multivariate Probabilistic CRPS Learning with an Application to Day-Ahead Electricity Prices, 2023, Jonathan Berrisch & Florian Ziel
We apply CRPS Learning to multivariate data. We extend the smoothing methods proposed in the original CRPS Learning paper and we apply the methodology to probabilistic forecasts of multivariate day-ahead electricity prices.
Modeling volatility and dependence of European carbon and energy prices, 2023, Jonathan Berrisch & Sven Pappert & Antonia Arsova & Florian Ziel
We developed a VECM-GARCH-COPULA model for EUA, coal, natural gas and oil prices. We use maximum likelihood to estimate the model parameters and forecast the prices in a one-step process.

Projects
profoc - An R Package for Probabilistic Forecast Combination
This package implements methods which are proposed and discussed in CRPS Learning.
CRAN | GitHub | Documentation
dccpp - An R Package for fast computation of the distance covariance and distance correlation
The computation cost is only O(n log(n)) for the distance correlation (see Chaudhuri, Hu, 2019, arXiv, elsevier). The functions are written entirely in C++ to speed up the computation.

sstudentt - A python package implementing the skewed-student-t distribution
This package implements the skewed student-t distribution in python. Parameterized as described in Wurtz et. al (2006) [1]. An implementation in R is already existent [2].

Development
I develop most of my projects in a docker container that is publicly available for reuse and inspiration. This container makes it easy to reproduce results or develop projects like the profoc R package.
The most convenient way to start is using VS-Code. You can find instructions in the GitHub Repo. However, the bare-bone Docker Container is also available and sufficient.
The Repository is available on GitHub.
The docker container is also available on GitHub
