In (a), we plot the cumulative number of reported cases obtained from the data (black dots) and the model (blue curve) on a period six times longer than in figure 8. In (b), we plot the daily rate of transmission obtained by using algorithm 1. We see that we can fit the data perfectly. But the method is very unstable like on figure 8. We obtain a rate of transmission that oscillates from positive to negative values back and forth.
