Eddington Weight

Eddington weight is a statistical measure used in astrophysics to evaluate how well a set of data fits a theoretical model, particularly in the context of stellar structures. Named after Sir Arthur Eddington, it assesses the likelihood that observations align with predictions based on fundamental physics. Essentially, it helps scientists determine whether differences between observed and expected data are due to random variation or suggest the model needs adjustment. The Eddington weight provides a quantitative way to judge the confidence level of a model's accuracy in describing physical phenomena like star stability or internal processes.
