Posterior parameter estimates and posterior predictive length of time between infection and reporting of African swine fever, South Korea, 2019*

Parameters Model output
Median (95% HDI) G-R DIC
Full model
Potentially contaminating vehicle movement (Pv) 53.9 (7.4–113.4) × 10−4 1.00 275.8 (null model: 284.6)
Wild boar cluster (Pw) 8.2 (0–19.0) × 10−4 1.00
Background (country, ) 0.03 (0–0.1) × 10−4 1.00
Background (epidemic region, ) 5.4 (1.1–11.2) × 10−4 1.00
Mean of the gamma distribution (α) 3.7 (1.0–8.8) 1.00
Variance of the gamma distribution (β) 44.6 (5.2–113.5) 1.00
Length of time between infection and reporting (D)† 4.3 (1.0–15.8)

*DIC, deviance information criteria; G-R, Gelman-Rubin convergence diagnostic; HDI, highest density interval; Pv, risk for infection resulting from 1 potentially contaminating vehicle movement; Pw, daily risk for infection resulting from being located in an African swine fever virus–positive wild boar cluster; PB1, daily background risk (country); PB2, daily background risk (epidemic region). †The distribution was obtained by simulating values from the gamma distribution, based on parameters α and β randomly sampled from their joint distribution.
