Statistical and economic evaluation of forecasts in electricity markets: Beyond RMSE and MAE
Energy Conversion and ManagementElectricity price forecasts are typically evaluated using accuracy measures such as RMSE and MAE, although these metrics often fail to reflect their economic value in operational decisions. This paper investigates which statistical properties of electricity price forecasts are most relevant for economic performance, using battery energy storage system (

Advanced Materials Interfaces, EarlyView.A DeepMD‐based molecular dynamics framework is developed to investigate water adsorption in ZIF‐90, explicitly accounting for framework flexibility. Results show that atomistic flexibility significantly influences adsorption energetics, diffusion, and structural correlations, yielding nearly constant heat of adsorption and enhanced mobility.

A forward demeaning transformation for a dynamic count panel data model [PDF]
In this note, a forward demeaning transformation is proposed for the linear feedback model with the explanatory variables being strictly exogenous on count panel data. This transformation is analogous to that proposed by Arellano and Bover (1995) for the
