Results and parameter estimates from the age and year-dependent model. Panels a) and d) show the year-dependent infection rates for dairy (red) and beef cattle (blue). The box represents the central 50% of the posterior distribution with the median marked by the central line. The outer whiskers represent the 95% CI and the outliers are shown as points. Panels b) and e) show the age-dependent infection risks for dairy and beef cattle. Panels c) and f) give the posterior density for the removal rate for dairy and beef.
