Common, parameter common to all insect species; varies, parameter varies among insect species; no difference, risk of transmission does not differ between clinical and subclinical animals; zero, parameter fixed at zero.
A model with a lower DIC is preferred to one with higher DIC. DIC, deviance information criterion. The model with its DIC shown in bold is the one preferred.
Level of viral DNA in blood or skin used as the proxy measure for infectiousness.
Although this model has a smaller DIC than the one shown in bold, the difference is less than two and the simpler model was preferred as it has the smaller number of parameters.
