Table 1. Training set WAIC scores for the three tested diseases and the three levels of model complexity.

model	campylobacteriosis	rotavirus	borreliosis
A	423279.3	349182.37	31359.62
B	420172.1	339143.27	(31359.62)
C	420010.64	338219.46	30643.49

Since for borreliosis the model is trained and evaluated only within the western state of Bavaria, the east/west feature is constantly zero, and the models A and B thus coincide.
