Note: β₀: the initial constant in the function of time-varying transmission rate; φ: the average unreported infection rate; λ₀: the initial constant in the function of time-varying recovery/mortality rate; m,k: the estimated constant in power/exponential functions of the time variable; AIC: model fitness based on Akaike information criterion.
