-1. Relationships - Compute correlation matrices
-2. Outcome - Analyze feature-outcome relationships (IC, importance, drift)
-3. Selection - Systematic feature filtering
-4. Visualization - Generate comprehensive plots

-Note: Outcome/diagnostics functionality is available in the separate ml4t-diagnostic library.
