Functions for evaluating and visualizing predictive model performance (specifically: binary classifiers) in the field of customer scoring. These metrics include lift, lift index, gain percentage, topdecile lift, F1score, expected misclassification cost and absolute misclassification cost. See Berry & Linoff (2004, ISBN:0471470643), Witten and Frank (2005, 0120884070) and Blattberg, Kim & Neslin (2008, ISBN:978–0–387–72578–9) for details. Visualization functions are included for lift charts and gain percentage charts. All metrics that require class predictions offer the possibility to dynamically determine cutoff values for transforming realvalued probability predictions into class predictions.
