Spatio-seasonal risk assessment of upward lightning at tall objects using meteorological reanalysis data

no code implementations18 Mar 2024 Isabell Stucke, Deborah Morgenstern, Georg J. Mayr, Thorsten Simon, Achim Zeileis, Gerhard Diendorfer, Wolfgang Schulz, Hannes Pichler

The model performs best in winter, with the highest predicted UL risk coinciding with observed peaks in measured lightning at tall objects.

Subgroup detection in linear growth curve models with generalized linear mixed model (GLMM) trees

no code implementations11 Sep 2023 Marjolein Fokkema, Achim Zeileis

Growth curve models are popular tools for studying the development of a response variable within subjects over time.

Upward lightning at wind turbines: Risk assessment from larger-scale meteorology

no code implementations9 Jan 2023 Isabell Stucke, Deborah Morgenstern, Thorsten Simon, Georg J. Mayr, Achim Zeileis, Gerhard Diendorfer, Wolfgang Schulz, Hannes Pichler

This leads to a large underestimation of the proportion of LLS-non-detectable UL at wind turbines, which is the dominant lightning type in the cold season.

What Makes Forest-Based Heterogeneous Treatment Effect Estimators Work?

2 code implementations21 Jun 2022 Susanne Dandl, Torsten Hothorn, Heidi Seibold, Erik Sverdrup, Stefan Wager, Achim Zeileis

A related approach, called "model-based forests", that is geared towards randomized trials and simultaneously captures effects of both prognostic and predictive variables, was introduced by Seibold, Zeileis and Hothorn (2018) along with a modular implementation in the R package model4you.

Hybrid Machine Learning Forecasts for the UEFA EURO 2020

1 code implementation7 Jun 2021 Andreas Groll, Lars Magnus Hvattum, Christophe Ley, Franziska Popp, Gunther Schauberger, Hans Van Eetvelde, Achim Zeileis

Based on the resulting estimates, the tournament is simulated repeatedly and winning probabilities are obtained for all teams.

bamlss: A Lego Toolbox for Flexible Bayesian Regression (and Beyond)

no code implementations25 Sep 2019 Nikolaus Umlauf, Nadja Klein, Thorsten Simon, Achim Zeileis

At the core of the package are algorithms for highly-efficient Bayesian estimation and inference that can be applied to generalized additive models (GAMs) or generalized additive models for location, scale, and shape (GAMLSS), also known as distributional regression.

Transformation Forests

no code implementations9 Jan 2017 Torsten Hothorn, Achim Zeileis

A more general understanding of regression models as models for conditional distributions allows much broader inference from such models, for example the computation of prediction intervals.
