UVRK-1 uses a remarkably simple 3-parameter recursion kernel that captures universal volatility dynamics across all domains:
Where:
• θ (theta) = Persistence/memory parameter (0.7-0.95)
• κ (kappa) = Mean-reversion sensitivity (1.0-1.6)
• ε (epsilon) = Innovation variance (~0.15)
The key innovation is the rank-based transformation using Φ⁻¹ (inverse normal CDF), which reveals universal volatility patterns hidden beneath surface-level price movements. This allows a single equation to work across radically different domains.
