\\Finally, the equation of the rate of individuals moving becoming removed (i.e. the rate of people who recover per unit time) is simply individuals who have recovered or died. This may be expressed as below:  \begin{equation*}  R_{t+1} - R_t = \frac{\mathrm{d} R}{\mathrm{d} t} = \gamma S_t I_t  \end{equation*}These are our equations for the basic dynamic equilibrium model (FIX ME)
