Understanding changes of the continuous ranked probability score using a homogeneous Gaussian approximation

M Leutbecher, T Haiden - Quarterly Journal of the Royal …, 2021 - Wiley Online Library
Improving ensemble forecasts is a complex process which involves proper scores such as

Evaluating forecasts for high-impact events using transformed kernel scores

S Allen, D Ginsbourger, J Ziegel - SIAM/ASA Journal on Uncertainty …, 2023 - SIAM
To account for uncertainties, forecasts for future events are commonly expressed in terms of
probability distributions over the set of possible outcomes. To evaluate the quality of such …

Forecasting conditional extreme quantiles for wind energy

C Gonçalves, L Cavalcante, M Brito, RJ Bessa… - Electric Power Systems …, 2021 - Elsevier
Probabilistic forecasting of distribution tails (ie, quantiles below 0.05 and above 0.95) is
challenging for non-parametric approaches since data for extreme events are scarce. A poor …

Improving probabilistic forecasts of extreme wind speeds by training statistical post-processing models with weighted scoring rules

JB Wessel, CAT Ferro, GR Evans… - arXiv preprint arXiv …, 2024 - arxiv.org
Accurate forecasts of extreme wind speeds are of high importance for many applications.
Such forecasts are usually generated by ensembles of numerical weather prediction (NWP) …

[HTML][HTML] Locally tail-scale invariant scoring rules for evaluation of extreme value forecasts

HK Olafsdottir, H Rootzén, D Bolin - International Journal of Forecasting, 2024 - Elsevier
Statistical analysis of extremes can be used to predict the probability of future extreme
events, such as large rainfalls or devastating windstorms. The quality of these forecasts can …

Why scoring functions cannot assess tail properties

JR Brehmer, K Strokorb - 2019 - projecteuclid.org
Motivated by the growing interest in sound forecast evaluation techniques with an emphasis
on distribution tails rather than average behaviour, we investigate a fundamental question …

Local scale invariance and robustness of proper scoring rules

D Bolin, J Wallin - Statistical Science, 2023 - projecteuclid.org
Averages of proper scoring rules are often used to rank probabilistic forecasts. In many
cases, the individual terms in these averages are based on observations and forecasts from …

Nonstationary seasonal model for daily mean temperature distribution bridging bulk and tails

M Krock, J Bessac, ML Stein, AH Monahan - Weather and Climate Extremes, 2022 - Elsevier
In traditional extreme value analysis, the bulk of the data is ignored, and only the tails of the
distribution are used for inference. Extreme observations are specified as values that exceed …
