Question 8: A prison system has historical data on prison inmates and wants to find what factors arerelated to recidivism (return to prison). What type of model would be used?
A. Segmentation model
B. Classification model
C. Association model
D. Anomaly model
Correct Answer: B
Explanation:
A classification model is tested by applying it to test data with known target values and comparing
the predicted values with the known values.
The test data must be compatible with the data used to build the model and must be prepared in
the same way that the build data was prepared. Typically the build data and test data come from
the same historical data set. A percentage of the records is used to build the model; the remaining
records are used to test the model.
Test metrics are used to assess how accurately the model predicts the known values. If the model
performs well and meets the business requirements, it can then be applied to new data to predict
the future.
