causes as censoring events, the concept of relative survival was developed by comparing the observed survival probability of a group of cancer patients with the survival of a âsimilarâ cancer-free group. Relative survival is defined as the ratio of the observed survival (all cause survival) of a cohort of cancer patients to the expected survival of a comparable set of cancer free individuals.
Survival data consist of a response variable that measures the duration of time until a specified event occurs (event time, failure time, or survival time) and possibly a set of independent variables thought to be associated with the failure time variable.edian Survival Time. This is the survival time at which the cumulative survival function is equal to 0.5. Other percentiles (25th and 75th percentile) of the cumulative survival function can be computed accordingly.
