Explanation:
Consistently recalibrating input parameters is crucial for ensuring uniform PIT distribution over time. Accurate inputs reflect evolving market dynamics, stabilizing predictions to align with both current conditions and expected risk patterns.
A is incorrect. Improving speed does not directly influence prediction accuracy regarding market dynamics.
B is incorrect. While testing is important, stabilizing with recalibrated parameters is essential for robust risk assessments.
C is incorrect. Simplifying portfolio elements may omit necessary granularity needed for precise risk evaluation.
