Figure 3
A line graph titled Accuracy and negative class performance measures. The horizontal axis represents time in quarters from 2015 quarter 2 to 2017 quarter 4. The vertical axis represents performance measures ranging from 0.4 to 1.0. The graph includes four lines: Accuracy, NPV, TNR, and Negative F1. Accuracy remains consistently high and stable around 1.0 throughout the period. NPV fluctuates slightly but generally stays around 0.7. TNR shows more variability, ranging between approximately 0.5 and 0.7. Negative F1 also varies, generally staying between 0.5 and 0.7. The lines for NPV, TNR, and Negative F1 show some peaks and troughs, indicating variability in performance measures over time.Accuracy versus performance measures for the negative class
