uppose the survival times (in months since transplant) for eight patients who received bone marrow transplants are 3.0, 4.5, 6.0, 11.0, 18.5, 20.0, 28.0, and 36.0. Assume no censoring.
- What is the median survival time?
- What is the mean survival time?
- Using 5 months as the interval, construct a life table for these data.
- Calculate a Kaplan-Meier curve for the survival distribution.
- Fit a negative exponential survival model to the data.
- Compare the fitted exponential to the Kaplan-Meier curve at the eight event times.
- Based on the comparison in 6, would you say the exponential is a good fit?
