Figure 5. Classical Additive Decomposition of monthly hMPV infections. Panel A shows the original non-detrended data of symptomatic hMPV episodes per month from 2011–2017. Panel B shows the trend-cycle component for monthly data (seasonal and remainder components extracted). Panel C shows the seasonal component extracted from the original data. Panel D shows the remainder component when the trend-cycle and seasonal component are extracted. The grey bars to the right of the panels denote the scales of each of the components.
