Anthrax carcass sample sizes and accuracy metrics for the ecological niche modeling experiment to estimate the potential geographic distribution of Bacillus anthracis on the landscape in the northern Madison study area, southwestern Montana, USA, based on a summer 2008 anthrax outbreak.

Metric	Model specifications
N to build models	85a
N to test models (independent)	29
Total omission	3.4
Average omission	4.7
Total commission	62.92
Average commission	41.41
AUCb	0.7416c,d

^aN was divided into 75% training and 25% testing at each model iteration.

^bAUC = area under curve.

^cZ = 8.72 (P < 0.001).

^dSE = 0.0530.
