A new position paper published on arXiv critiques the prevalent use of the C-index metric in survival analysis, arguing that it often misaligns with the actual modeling objectives and can be misleading due to implicit censoring assumptions. The authors propose a 'double-helix ladder' framework to ensure evaluation metrics are aligned with modeling assumptions, emphasizing that proper evaluation is crucial for accurate model comparisons. The paper offers practical guidance for researchers on how to select and apply appropriate evaluation metrics in survival analysis. AI
