The Effect of Partial and Temporary Vaccination on African Swine Fever Eradication Rates
Table 2
Estimates of the regression coefficients derived from a multinomial regression model, in which the year of ASF eradication was used as response variable and a set of ecological, management-related, and epidemiological parameters as predictors.
