Feb 5, 2021 to Oct 12, 2026Model Insight
Estimated persistence of 1.000 is at or above 1 (non-stationary): volatility shocks do not decay and the long-run variance is undefined, so long-horizon forecasts should be treated with caution. The volatility power δ = 1.51 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
