Bayesian structured additive quantile regression for inflated bounded data

Francisco F. Queiroz, Johannes Brachem, Paul F. V. Wiemann +1

Bounded continuous data on the unit interval frequently arise in applied fields and often exhibit a non-negligible proportion of observations at the boundaries. Inflated regression…

Data-Efficient Generative Modeling of Non-Gaussian Global Climate Fields via Scalable Composite Transformations

Johannes Brachem, Paul F. V. Wiemann, Matthias Katzfuss

Quantifying uncertainty in climate-model output requires characterizing internal variability, often through large ensembles of physical climate-model runs. Since each additional en…

Generative multi-scale modeling via spatial autoregressive transport maps

Alejandro Calle-Saldarriaga, Paul F. V. Wiemann, Matthias Katzfuss

Spatial fields in the Earth and environmental sciences are often available at multiple scales or resolutions. While coarse-scale data (e.g., from global circulation models) are oft…

Stochastic Variational Inference for Structured Additive Distributional Regression

Gianmarco Callegher, Thomas Kneib, Johannes Söding +1

Structured additive distributional regression extends generalized additive models by allowing all parameters of a response distribution to depend on structured additive predictors.…

Bayesian Penalized Transformation Models: Structured Additive Location-Scale Regression for Arbitrary Conditional Distributions

Johannes Brachem, Paul F. V. Wiemann, Thomas Kneib

Penalized transformation models (PTMs) are a semiparametric location-scale regression family that estimate a response's conditional distribution directly from the data, and model t…

Bayesian nonparametric generative modeling of large multivariate non-Gaussian spatial fields

Paul F. V. Wiemann, Matthias Katzfuss

Multivariate spatial fields are of interest in many applications, including climate model emulation. Not only can the marginal spatial fields be subject to nonstationarity, but the…
