Fig. 2From: Comparison of time-series models for monitoring temporal trends in endemic diseases sero-prevalence: lessons from porcine reproductive and respiratory syndrome in Danish swine herdsWavelet coherence plot at scale-scale j = 1. The x-axis indicates specific time points (weeks) observed in the time-series since the first observation (i.e. t = 1 corresponds to 23rd July 2012 until 31st December 2014). The coherence obtained for the Dynamic Linear Model (DLM), from the Generalized Dynamic Linear Model (DGLM) and from the Holt’s linear trend method (HM) are represented Back to article page
