Comparison between filtered means obtained from the different models and Porcine Reproductive and Respiratory Syndrome sero-prevalence between January 2010 and December 2014. The filtering values obtained from the Dynamic Linear Model (DLM), from the Generalized Dynamic Linear Model (DGLM) and from the Holt’s linear trend method (HM) are represented for the different herd types. The Red SPF herds are tested on a monthly basis for PRRS; the Blue SPF herds are tested at least once a year for PRRS; the Non SPF herds are tested with other frequencies for PRRS
