Fast and Order-invariant Inference in Bayesian VARs with Non-Parametric Shocks

Coarsened Bayesian VARs -- Correcting BVARs for Incorrect Specification

no code implementations16 Apr 2023 Florian Huber, Massimiliano Marcellino

Model mis-specification in multivariate econometric models can strongly influence quantities of interest such as structural parameters, forecast distributions or responses to structural shocks, even more so if higher-order forecasts or responses are considered, due to parameter convolution.

Grouping Shapley Value Feature Importances of Random Forests for explainable Yield Prediction

no code implementations14 Apr 2023 Florian Huber, Hannes Engler, Anna Kicherer, Katja Herzog, Reinhard Töpfer, Volker Steinhage

Explainability in yield prediction helps us fully explore the potential of machine learning models that are already able to achieve high accuracy for a variety of yield prediction scenarios.

A tale of two tails: 130 years of growth-at-risk

no code implementations17 Feb 2023 Martin Gächter, Elias Hasler, Florian Huber

In this context, the paper also adds to the financial cycle literature by completing the picture of drivers (and risks) for both booms and recessions over time.

Nonlinearities in Macroeconomic Tail Risk through the Lens of Big Data Quantile Regressions

no code implementations31 Jan 2023 Jan Prüser, Florian Huber

Modeling and predicting extreme movements in GDP is notoriously difficult and the selection of appropriate covariates and/or possible forms of nonlinearities are key in obtaining precise forecasts.

Extreme Gradient Boosting for Yield Estimation compared with Deep Learning Approaches

no code implementations26 Aug 2022 Florian Huber, Artem Yushchenko, Benedikt Stratmann, Volker Steinhage

While the accuracies reached with those approaches are promising, the needed amounts of data and the ``black-box'' nature can restrict the application of Deep Learning methods.

Forecasting euro area inflation using a huge panel of survey expectations

no code implementations25 Jul 2022 Florian Huber, Luca Onorante, Michael Pfarrhofer

In this paper, we forecast euro area inflation and its main components using an econometric model which exploits a massive number of time series on survey expectations for the European Commission's Business and Consumer Survey.

Unsupervised Features Ranking via Coalitional Game Theory for Categorical Data

1 code implementation17 May 2022 Chiara Balestra, Florian Huber, Andreas Mayr, Emmanuel Müller

Unsupervised feature selection aims to reduce the number of features, often using feature importance scores to quantify the relevancy of single features to the task at hand.

Forecasting US Inflation Using Bayesian Nonparametric Models

no code implementations28 Feb 2022 Todd E. Clark, Florian Huber, Gary Koop, Massimiliano Marcellino

The relationship between inflation and predictors such as unemployment is potentially nonlinear with a strength that varies over time, and prediction errors error may be subject to large, asymmetric shocks.
