Table 3.

Summary of results of best temporal linear mixed-effects model, with population-adjusted Campylobacter case rates per month as the response, and subcatchment number as the random effect. qo is saturated surface-water overland flow from Topmodel; Ep is potential evapotranspiration. Standard deviation of residual random effects = 0.3104; log-likelihood = −496.95; BIC = 1099.51
