A two‐scale framework bridges process‐level physics and system‐level decision‐making for electrified green methanol production. Replacing computationally demanding reactor simulations with an interpretable symbolic‐regression surrogate enables rapid techno‐economic and life‐cycle assessment. The framework reveals how process performance propagates into

Beta Estimation Under Infrequent Trading: A Machine Learning Approach
ABSTRACT When shares are traded infrequently, beta estimates are often severely biased. We find that machine learning methods significantly improve forecasts of the conventional beta proxy in this infrequently traded market. They generate superior beta forecasts, statistically and economically outperforming the traditional model used by practitioners ...
