Chapter 2: Modeling Process

[bgreenwell]

• The Class imbalances discussion should be moved into its own section; we should also call out issues around re-balancing classes (which often causes more problems than it solves).
• The MSE in classification is more often referred to as the Brier score. We should also highlight that the Brier score and log loss are examples of proper scoring rules; more useful for probability predictions and assessing accuracy of probabilities.
• Lift charts and calibration/reliability diagrams should be introduced (and used in some of the examples later in the book).
