| Outline of Final Research Achievements |
This project investigated a concordance probability for time-to-event data called the C-index and its applicability to Survival Tree. The C-index can be seen as an extension of the area under the ROC curve for binary data. However, the existence of censored individuals causes a bias in estimating the C-index. We proposed some estimators for the C-index which reduce the bias, and demonstrated their superiority to the existing estimators via numerical experiments.
