Survival Analysis in R
kursunun bir parçasıdırEgzersiz talimatları
- Estimate a survivor function for the breast cancer patients.
- Visualize the estimated survival function using the function
ggsurvplot(). - Add a risk table to the plot showing the number of patients under observation. This can be done using the
risk.tableargument. - Add a line showing the median survival time to the plot. This can be done using the
surv.median.lineargument.
