Table 2.
Multi-state models for free-ranging eastern foxsnake (Pantherophis vulpinus; n = 17) exposed to Ophidiomyces ophidiicola, ranked by model weight.
| Model | k | AICc | ΔAICc | w | Deviance |
|---|---|---|---|---|---|
| S(~ 1)p(~ 1)ψ(~ Simple State) | 3 | 206.29 | 0.00 | 0.74 | 157.08 |
| S(~ 1)p(~ 1)ψ(~ State) | 5 | 208.45 | 2.17 | 0.25 | 154.94 |
| S(~ 1)p(~ 1)ψ(~ 1) | 2 | 216.12 | 9.83 | 0.01 | 169.02 |
Simple State = transitions to Dead versus transitions between No Clinical Signs and Clinically Positive”; State = all unique transitions among states. Variables: S = survival fixed to 1, p = probability of detecting the snake, ψ = probability of transitioning among No Clinical Signs, Clinically Positive, and Dead states (transitions from Dead state fixed to 0). k = number of parameters, AICc = small-sample-corrected Akaike’s information criterion, w = model weight.
