Complexity vs Empirical Score

• Math Complexity: 3.0/10
• Empirical Rigor: 6.0/10
• Quadrant: Street Traders — practical and empirical, lighter on theory

Why this score: The paper focuses on empirical analysis of cross-sectional credit market data with clear real-world applicability, but its mathematical depth appears limited to basic econometric models without advanced derivations.
