Figure 4From: The asymptotic behavior of a stochastic SIS epidemic model with vaccination Computer simulation of the path \(\pmb{S(t)}\) , \(\pmb{I(t)}\) , and \(\pmb{V(t)}\) of the SDE model ( 1.3 ) for \(\pmb{\sigma=0.04}\) , using the EM method with step size \(\pmb{\Delta t = 0.001}\) and the initial value \(\pmb{(S(0),I(0),V(0))=(0.8,0.4,0.5)}\) .
