Skill vs. persistence
—AVG —
Persistence advantageAdaptive skill advantage
Rolling forecast skill relative to a persistence baseline. Zero means equal error; positive values favor the adaptive model, while negative values favor repeating the previous observation. As a practical guide, 0–10 indicates only a slight advantage, 10–20 a modest advantage, 20–30 good skill, 30–40 strong skill, and values above 40 very strong skill. These ranges are interpretive rather than universal and should be considered alongside the signal, window length, and evaluation conditions.
Adaptive plasticity
—AVG —
How strongly the model is currently revising itself in response to drift and surprise.
Drift
—AVG —
How strongly the signal’s recent direction and pace are departing from its established local pattern.
