Note: β’₀: the initial constant in the time-varying function of the transmission rate and the unreported rate of new reported infections; φ₀: the initial constant in the time-varying function of the unreported rate of cumulative reported infections; λ₀: the initial constant in the function of time-varying recovery/mortality rate; m,n,k: the estimated constants in power/exponential functions of the time variable; AIC: model fitness based on Akaike information criterion.
