Description Usage Format Note Source Examples
The file contains the data on 65 transplanted patients, consisting of the patient's age at transplantation, prior open-heart surgery (1 = yes, 0 = no), a censoring indicator (1 = yes, 0 = no), the survival time in days after transplant , a score representing the mismatch between the patient's and the donor's tissue type (values range from 0.00 to 3.05), and an indicator for death by rejection (1 = yes, 0 = no). One zero survival time is recoded to 0.5. There are 41 deaths and 24 censored survivals, with 39 distinct death times.
