Huber loss, its asymmetric variants and their associated functionals (here named functionals) are studied in the context of point forecasting forecast evaluation. The functional a distribution is set minimizers expected (asymmetric) an intermediary between quantile corresponding expectile, also arises M-estimation. Each elicitable, generating precise score, subject to weak regularity conditions on class probability distributions, has complete characterization consistent scoring functions....
Abstract. Risk matrices are widely used across a range of fields and have found increasing utility in warning decision practices globally. However, their application this context presents challenges, which from potentially perverse outcomes to lack objective verification (i.e., evaluation) methods. This paper introduces coherent framework for generating multi-level warnings risk address these challenges. The proposed is general, based on probabilistic forecasts hazard severity or impact...
We present abstract inhomogeneous Strichartz estimates for dispersive operators, extending previous work by M. Keel and T. Tao on the one hand, generalising results of D. Foschi, Vilela, Nakamura Ozawa other hand. It is shown that these imply new wave equation some Schrödinger equations involving potentials.
Abstract Operational agencies face significant challenges related to the verification and evaluation of weather forecasts. These were investigated in a series online workshops polls engaging operational personnel from six countries. Five key themes emerged: inadequate approaches for both existing emerging products; incomplete uncertain observations; difficulties accurately capturing users’ real-world experiences using simplified metrics; poor communication understanding forecasts complex...
An unusual combination of circumstances occurring during an Atlantic crossing a highspeed containership created situation where the rudder, acting in response to automatic steering control demands, caused excessive ship rolling. Further investigation revealed existence unstable condition due asymmetrical hydrodynamic and mechanical characteristics interrelationship motion actuation. Similar has been noted on other high-speed vessels is cause for major concern future operations. The elements...
The use of tiered warnings and multicategorical forecasts are ubiquitous in meteorological operations. Here, a flexible family scoring functions is presented for evaluating the performance ordered forecasts. Each score has risk parameter $\alpha$, selected specific case, so that it consistent with forecast directive based on fixed threshold probability $1-\alpha$ (equivalently, $\alpha$-quantile mapping). also use-case weights forecasters who accurately discriminate between categorical...
Forecast verification is critical for continuous improvement in meteorological organizations. The Jive system was originally developed to assess the accuracy of public weather forecasts issued by Australian Bureau Meteorology. It started as a research project 2015 and gradually evolved into operational that went live 2022. includes daily dashboards forecasters visualize recent forecast performance "Evidence Targeted Automation" exploring competing systems. Additionally, there Jupyter...
Abstract A user-focused verification approach for evaluating probability forecasts of binary outcomes (also known as probabilistic classifiers) is demonstrated that (i) based on proper scoring rules, (ii) focuses user decision thresholds, and (iii) provides actionable insights. It argued when categorical performance diagrams the critical success index are used to evaluate overall predictive performance, rather than discrimination ability forecasts, they may produce misleading results....
The employment and unemployment measures gathered by the United States Bureau of Census published Labor Statistics are most complete comprehensive labor-force data developed any nation. technical excellence, however, has not made these immune from criticism. Taking exception to conditions reported government bureaus, some detractors have blamed messenger for message, charging that excessive is a cabal hatched bureaucrats scare public into supporting new social programs which would expand...
