The optimal values of the parameters β, γ in the SIR model and β, σ, γ in the SEIR model were obtained by performing a local adjoint sensitivity analysis (Cao et al. 2003; Rackauckas et al. 2019) of the ODE problems in these models, by minimizing the mean square error loss function L(β, σ, γ) defined as L(β, σ, γ) = log(I(t)) − log(I data (t)) 2 + log(R(t)) − log(R data (t)) 2 (4.9)
