• Directional accuracy evaluated for rates, prices and market movements
• Performance thresholds linked to planning tolerances and intervention rules

Participants can produce and assess forecast intervals for financial planning decisions.

• Quantile regression estimates downside, central and upside forecast values
• Prediction intervals distinguish uncertainty from alternative business scenarios

Participants can explain model outputs and challenge implausible forecast drivers.

• Permutation importance tests sensitivity to individual model input features

• Partial dependence identifies average model responses to changing inputs
• Individual conditional expectation plots expose heterogeneous feature effects
