Overview
Kendall W - Coefficient of concordance for multiple rankings
- Output
- robustness score, higher is better
- Data
- Crisp, complete numeric matrix
- Size
- 2+ alternatives, 3-12 criteria works best
- Used for
- Sensitivity analysis, uncertainty quantification
How it works
- 1
Validate inputs for kendall-w.
Kendall 1939, (pending PDF page verification)
Look elsewhere when
- •Quick analysis needed. Defer robustness check.
Assumptions to verify
- A base ranking method is selected
- Computational budget for repeated runs
Edge cases and pitfalls
Applying KENDALL-W without verifying this assumption.
Requirement: A base ranking method is selected
Applying KENDALL-W without verifying this assumption.
Requirement: Computational budget for repeated runs
Using KENDALL-W when: Quick analysis needed → defer robustness check.
An alternative method is recommended in this situation.
