Description of the models compared in the ten-fold cross-validation exercise

Models	Assumptions	Parameters
1 – No correlation	No spatial and no pathogen correlation	ρ = 0; Φ > > 0
2 – Spatial	Accounts for spatial correlation but not for pathogen correlation	ρ = 0; Φ estimated
3 – Pathogen	Accounts for pathogen correlation but not for spatial correlation	ρ is estimated; Φ > > 0
4 – Pathogen + Spatial	Accounts for pathogen and spatial correlation	ρ and Φ are both estimated
