Collaborative nowcasting of COVID-19 hospitalization incidences in Germany
Fig 7
Shown is the mean WIS for the national level (top) and averaged across states (middle) and age groups (bottom). The first panel in each row displays the average across all horizons (on the absolute and relative scales). The decomposition into nowcast spread, underprediction, and overprediction (see Section 2.5) is represented by blocks of different color intensities. The absolute error is indicated by a diamond (⋄). The second and third panels in each row show the mean WIS and the relative WIS, respectively, stratified by horizon.
