Weight Sensitivity Analysis: Stability intervals for criterion weights
Saltelli, A., Tarantola, S., Campolongo, F., Ratto, M. · 2004
Overview
Robustness diagnostic: weight stability intervals. Output typically robustness_score (higher value = preferred).
Strengths
- •Method-specific: Robustness diagnostic: weight stability intervals
Limitations
- •Assumes: A base ranking method is selected
- •Assumes: Computational budget for repeated runs
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •A base ranking method is selected
- •Computational budget for repeated runs
When not to use
- •Quick analysis needed → defer robustness check
Edge cases
- •See F.steps and D.parameters for WEIGHT-SENSITIVITY-specific edge handling. recommendation_metadata.assumptions_to_verify also lists boundary conditions.
Common pitfalls
- •Hatalı: 'WEIGHT-SENSITIVITY bu varsayımı kontrol etmeden uygulamak'. Doğrusu: A base ranking method is selected
- •Hatalı: 'WEIGHT-SENSITIVITY bu varsayımı kontrol etmeden uygulamak'. Doğrusu: Computational budget for repeated runs
- •Hatalı: WEIGHT-SENSITIVITY'yi 'Quick analysis needed → defer robustness check' durumunda kullanmak: recommendation_metadata.not_recommended_when alternatif öneriyor.
