From: A paradox of epidemics between the state and parameter spaces

(a) and (b) represent the dependence of SΔt on the two parameters Δβ and T in state space, respectively, where the “squares” denote the numerical simulations and the solid lines are the theoretical results from Eqs (11) and (16). (c) and (d) represent the corresponding S t of (a) and (b) in state space, respectively, where the “squares” denote the numerical simulations and the solid lines are the theoretical results from Eqs (11) and (16). The other parameters are the same as in Fig. 2(c) and (d).
