Analysis of different observable combinations. (A) Schematic of the SEIRD model. (B,C,D) Fitting results for observation scenarios O1, O2, and O3 assuming log-normally distributed measurement noise. The simulation for the maximum likelihood estimate (line) and interval for one standard deviation of the inferred noise level (shaded area) is depicted. The upper bound for the inverse of the rate constants was set to 182 days and for the initial conditions to 1000 individuals.
