Figure A2.

Model validation logarithmic scores. Maps are color coded to illustrate error geographic distribution as assessed using logarithmic scoring for case count thresholds at 1, 2, 5, and 10 neuroinvasive disease cases. Lower values (yellows) indicate locations with relatively high predictive accuracy and darker tones point to areas of poorer performance. Logarithmic scores showed improved accuracy with increasing case counts and US-wide mean scores of 0.53, 0.18, 0.06, and 0.02 for 1, 2, 5, and 10 cases, respectively.
