Bad rates
With acceptance rate in mind, you can now analyze the bad rate within the accepted loans. This way you will be able to see the percentage of defaults that have been accepted.
Think about the impact of the acceptance rate and bad rate. We set an acceptance rate to have fewer defaults in the portfolio because defaults are more costly. Will the bad rate be less than the percentage of defaults in the test data?
The predictions data frame test_pred_df
has been loaded into the workspace.
This exercise is part of the course
Credit Risk Modeling in Python
Exercise instructions
- Print the first five rows of the predictions data frame.
- Create a subset called
accepted_loans
which only contains loans where the predicted loan status is0
. - Calculate the bad rate based on
true_loan_status
of the subset usingsum()
and.count()
.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Print the top 5 rows of the new data frame
print(____.____())
# Create a subset of only accepted loans
____ = ____[____['pred_loan_status'] == ____]
# Calculate the bad rate
print(np.____(____['true_loan_status']) / ____['true_loan_status'].____())
