Models considered for explaining the probability of tuberculosis infection in the wild boar.

Model selection based on generalized additive modelling for exploring the temporal variation in the probability of tuberculosis infection determined in 267 adult, 97 juvenile and 70 yearling wild boars harvested in the main tuberculosis area and outlying areas (TBA and OA) in the National Game Reserve “Ports de Tortosa i Beseït”. Harv1 means the total number of wild boars harvested in the previous harvesting season, whereas Harv3 is the total number of wild boars harvested during the three seasons before the current one. K = effective number of parameters in the additive modelling, AIC = Akaike Information Criterion, Δi = difference of AIC with respect to the best model, wi = Akaike weight, Mo = null model only with the constant term. In bold the best model for explaining the observed TB probability of infection.
