Figure 1

Comparison between our model and real data. In this figure we show a comparison between our model given by the system of nonlinear differential equations (1) and real data coming from the WHO included as Table 1. The values of the parameters are \(m=80\), \(q=0.030\) (left) and \(m=75\), \(q=0.067\) (right). The errors using \(\ell^{2}\) norm are 5,185.344 and 5,309.831, respectively.
