Out of the 100 test loan application records, our model correctly predicted that 59 did not default and 14 did default, resulting in an accuracy of 73 percent and an error rate of 27 percent. This is somewhat worse than its performance on the training data, but not unexpected, given that a model's performance is often worse on unseen data. Also note that the model only correctly predicted 14 of the 33 actual loan defaults in the test data, or 42 percent. Unfortunately, this type of error is a potentially very costly mistake, as the bank loses money on each default. Let's see if we can improve the result with a bit more effort.
