To run this hidden model with constant N = S + M + H + C, one needs initial values and good estimates for β and γ, which are not the ones of the Johns Hopkins Data Model of section 3.3. These yield estimates for the parameters of the full SIR model that replace the earlier time series from the Johns Hopkins Data Model in section 3.3. Note that the only ingredients beside the Johns Hopkins data are the number k for the k-day rule, the Infection Fatality Rate γ IF from the literature, and the backlog m for estimation of constants from time series. ./cache/cord-190296-erpoh5he.txt ./txt/cord-190296-erpoh5he.txt
