Computing a Weibull model and the survival curves
In this exercise we will reproduce the example from the video using the following steps:
- Compute Weibull model
- Decide on "imaginary patients"
- Compute survival curves
- Create
data.framewith survival curve information - Plot
In this exercise, we will focus on the first three steps. The next exercise will cover the remaining steps.
The survival, survminer, and reshape2 packages and the GBSG2 data are loaded for you in this exercise.
