Senators' terms in office
You want to compare if senators from Quebec tend to serve a different term length than those from British Columbia. One simple method is to plot their Kaplan-Meier survival functions on the same graph.
The DataFrame containing British Columbia senator term durations information is called bc_df. It contains columns
name: the name the of senatordiff_days: the duration of the senator in officeobserved: whether the end of the term is observed (1 or 0)
The survival curve of Quebec senators has been plotted on a pyplot object called senator_fig, and a KaplanMeierFitter instance called kmf has been created.
Additionally, 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.
