Fig. 3From: Modeling the spatio-temporal dynamics of porcine reproductive & respiratory syndrome cases at farm level using geographical distance and pig trade network matricesPosterior mean of the differential time effect (δ i ) for reported PRRS cases of 124 farms from 2012 to 2015. If δ i < 0 then the farm specific trend is less steep than the mean trend, whilst δ i > 0 implies that the farm specific trend is steeper than the mean trend.
