This paper explores conformal prediction methods for competing risks, focusing on how censoring affects coverage guarantees. The authors investigate the impact of complete-case calibration, which only considers fully observed data, and demonstrate that it can lead to under-coverage, especially when censoring is prevalent. They propose using weights derived from a correctly specified censoring model to maintain nominal coverage, extending prior work on cause labels and establishing a finite-sample coverage lower bound that accounts for censoring model error.
