WebJan 21, 2024 · The fact that we can fit these curves does not make the models correct. The underlying mechanisms are much more complex than the assumed mechanisms. This is eventually the conclusion of Aaron King's introduction. What does this plot tell us? Essentially, the deterministic SIR model, as we’ve written it, cannot capture the shape of … WebSince S + I + R is assumed to be constant, the sum S′ + I′ + R′ of the rates of change of the three subpopulations must be zero – any change in one of these quantities is offset by changes in the others. That is, by the above formulas for S′ and R′, 0 = S ′+I +R′ = −aSI +I′ +bI or, solving for I′, I′ = aSI − bI.
