Table 6. Parameter estimates for the 2013/14 dengue epidemic when the model was fitted to MIA or ELISA data.
Median estimates are shown, with 95% credible intervals shown in parentheses. Mean is the average basic reproduction number over a year. Proportion reported was calculated by sampling from the negative binomial distribution that defines the model observation process (i.e. the credible interval reflects both underreporting and dispersion in weekly case reporting). and denote the number of initially infectious individuals in the younger and older age group respectively.

Mean | 1.12 (1.02–1.25) | 1.49 (1.35–1.69) |
Peak | 1.87 (1.7–2.07) | 2.5 (2.29–2.81) |
Control reduction | 0.57 (0.42–0.82) | 0.70 (0.37–0.95) |
Proportion reported, lab (%) | 11 (1.1–39) | 13 (2.6–36) |
Proportion reported, DLI (%) | 9.3 (0.99–37) | 12 (2.8–35) |
140 (18–550) | 0.98 (0.21–3.8) | |
130 (19–680) | 1.3 (0.0094–57) |
