2D histogram results for the S, E, I, R stocks with different age groups of the minimum discrepancy model with splitting the age groups at 15 years by incorporating the empirical data across all timeframe.
The results shown consider both the yearly and monthly empirical data, with monthly discrepancy 90.7, the sum of all age groups discrepancy in Month is 36.9. (a) across all population. (b) the child age group (those within their first 15 years of life). (c) the adult age group (years 15 and up).
