The DataFrame is called recur and contains columns

  • age: the age of the patient;
  • time_0: the time that the patient received the treatment;
  • time_1: the last time of an event, or the last time you measured a censored patient;
  • censor: whether the event is censored;

The pandas package is loaded as pd, the KaplanMeierFitter class is imported from lifelines, and the pyplot module has been import from matplotlib as plt.
