Snippet: We fit, in Figure 1 , the curve of current infectives (I) with (3) and the curve of cumulative removed cases (R) with (4) simultaneously. During the fitting procedure, the parameters Ï 1 and Ï 2 are shared, and others are free to vary. The fit method is minimisation of a chi-square (χ 2 ) using data errors. The data errors are estimated on the base of single counting uncertainty. Let A i , C i and D i separately stand for cumulative confirmed .....
