Computing a Cox model
We have a dataset of lung cancer patients. We want to know if their performance score (variable performance) is associated with their survival time.
The performance score measures how well a patient can perform usual daily activities (bad=0, good=100).
The survival package and the dat dataset are already loaded for you.
