Multinomial approximation to the Kolmogorov Forward Equation for jump (population) processes

Figures & data

Figure 1. Simulation outputs of the SIRS model for $S_0=6000,rr=0.8,ri=0.0002,rs=0.02$ and $dt=0.02$ for the approximated stochastic simulation. The upper left panel displays the average time-trace of the number of infected individuals. Upper right: average trace of the trajectory in the $(S,I)$ plane. The bottom panel displays the number of process in which the infected population became extinct. In all cases, ${10}^4$simulations where performed.
