Evaluating Forecasts at Multiple Horizons: An Extension of the Diebold–Mariano Approach

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Forecast accuracy tests are fundamental tools for comparing competing predictive models. The widely used Diebold–Mariano (DM) test assesses whether differences in forecast errors are statistically significant. However, its standard form is limited to pairwise comparisons at a single forecast horizon.

Revealing Perovskite Crystallization and Degradation With Grazing‐Incidence Wide‐Angle X‐Ray Scattering: Kinetics, Phase Analysis and Modulation Strategies

open access: yesInformation &Functional Materials, EarlyView.
The ability to probe surface‐to‐bulk structural gradients and detect minority phases makes GIWAXS indispensable for understanding the complex crystallization kinetics that ultimately determine perovskite film quality and device performance. By monitoring the nucleation, growth, and phase transition processes, GIWAXS provides critical insights for ...

Derivation and Validation of a Predictive Model for Advanced Colorectal Neoplasia Among Average‐Risk Adults in China

open access: yesInternational Journal of Cancer, EarlyView.
Efficient pre‐colonoscopy risk stratification tools are needed, especially in China. Using multicenter colorectal cancer screening data from Shandong Province, the authors developed and validated a risk prediction model for advanced colorectal neoplasia in asymptomatic individuals using sociodemographic characteristics, lifestyle factors, and medical ...

Brexit and Its Impact on EU Financial Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.

Motive and Opportunity: Order Choice in a Limit Order Book With Dispersed Information

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We test predictions of market microstructure theory relating to the determinants of order choice in a limit order book where information is dispersed among traders. Using an experimental limit order book, with a large state space, we find that informed traders exhibit patience, compatible with the ‘waiting game’ behaviour described in Foster ...
