Discretization of a certain variable
In order to make predictor insight graphs for continuous variables, you first need to discretize them. In Python, you can discretize pandas columns using the qcut method.
To check whether the variable was nicely discretized, you can verify that the bins have equal size using the groupby method:
print(basetable.groupby("discretized_variable").size()

- Use the method
qcutto discretize the variabletime_since_last_donationin 10 groups. Assing this variable to a new column called "bins_recency". - Use the method
groupbyto verify that the bins have about equal size.
