Root mean square error (E) for the \(\beta\) (top panel), \(\gamma\) (middle panel) and \(\tau\) (bottom panel). The x-axis represents the time of the trajectories in weeks. Values of E closer to zero mean better predictions. Each plot contains the performance related to each sample considered. Sample 1 contains 5000 observation, Sample 2 contains 10000 observations, Sample 3 contains 15000 observation and Sample 4 contains 20000
