Sep 23, 2021 to Jul 10, 2026Model Insight
The estimated Student-t degrees of freedom v = 2.00 sit at the infinite-variance boundary (v → 2): the model is attributing extreme moves to heavy tails rather than to volatility, so the volatility scale is unreliable here. See the boundary-parameters flag.
