Explanation:
Probability Integral Transforms (PITs) are frequently used to evaluate the accuracy of density forecasts. According to Rosenblatt's transformation, if a model's density forecast is accurately specified, the resulting empirical PITs will be independent and uniformly distributed on the interval [0,1]. Therefore, ensuring that the transformed PIT results plot uniformly across [0,1] provides evidence that the predictions are valid.

Reach cross-sectional stability through diverse market metrics.
C
Ensure that transformed PIT results plot evenly over [0,1].
D
Drive consistency in parameter inputs at all risk thresholds.
