Pooling of forecasts [PDF]

open access: yesThe Econometrics Journal, 2004
Summary: We consider forecasting using a combination, when no model coincides with a non-constant data generation process (DGP). Practical experience suggests that combining forecasts adds value, and can even dominate the best individual device. We show why this can occur when forecasting models are differentially misspecified, and is likely to occur ...

Effect of non-hydrostatic stress on the structure and elasticity of NaCl by first-principles calculation

open access: yesAIP Advances, 2019
Non-hydrostatic stresses have a unique influence on materials. To understand the effect of non-hydrostatic stress on NaCl, one of the most widely used pressure calibrant in high-pressure experiments, the lattice constants, density, elastic modulus, Young’

Forecasting Breaks and Forecasting During Breaks [PDF]

open access: yes, 2012
AbstractThis article, which proposes a new approach to forecasting breaks by focusing on the role of information, begins by outlining the eight conditions that are necessary to successfully forecast a break. Section 2 then considers the concepts of unpredictability and information to address the first necessary condition.

Loop Current SSH Forecasting: A New Domain Partitioning Approach for a Machine Learning Model

open access: yesForecasting, 2021
A divide-and-conquer (DAC) machine learning approach was first proposed by Wang et al. to forecast the sea surface height (SSH) of the Loop Current System (LCS) in the Gulf of Mexico.

Advances in forecasting with artificial neural networks [PDF]

open access: yes, 2010
There is decades long research interest in artificial neural networks (ANNs) that has led to several successful applications. In forecasting, both in theoretical and empirical works, ANNs have shown evidence of good performance, in many cases ...

Goes-13 IR Images for Rainfall Forecasting in Hurricane Storms

open access: yesForecasting, 2020
Currently, it is possible to access a large amount of satellite weather information from monitoring and forecasting severe storms. However, there are no methods of employing satellite images that can improve real-time early warning systems in different ...

The Effect of Lead-Time Weather Forecast Uncertainty on Outage Prediction Modeling

open access: yesForecasting, 2021
Weather-related power outages affect millions of utility customers every year. Predicting storm outages with lead times of up to five days could help utilities to allocate crews and resources and devise cost-effective restoration plans that meet the ...
