Weight of Evidence (WoE) encoding

WoE encoding was originally developed for the credit and financial industries. It is used to build predictive models for assessing loan default risk in those industries. WoE quantifies the effectiveness of a grouping method by distinguishing between good and bad risks. This technique is particularly well suited for logistic regression as it establishes a monotonic relationship between the target variable and the independent variables, ordering the categories on a logistic scale. In this section, you can try it on sample data:

  1. Start by importing pandas and importing train_test_split from scikit-learn to prepare for applying the encoding. Import matplotlib.pyplot and numpy, which you will use to make graphs to show the relationship between the encoded categorical variables and the target variable:
    import pandas as pd
    from sklearn.model_selection import train_test_split
    import matplotlib.pyplot as plt
    import numpy as np
  2. Set up the sample data...
