Table III.
Descriptive statistics and distributions that best fit the stages of serotype O foot-and-mouth disease virus (FMDV) infection in an individual data meta-analysis exercise. Data were fit using equal width intervals for continuous and discrete data (Poisson) distributions. Bolded letters indicates a p > 0.05 value, which indicates the theoretical distribution fit the data well.
FMD stage | Animal species | No. | Mean, median (25th, 75th percentile) | Distribution (parameters) | Poisson (λ) |
