Autocorrelation plots, partial autocorrelation plots of the residuals and scatter plot of residuals against the predicted values of the seasonal autoregressive moving average SARIMA model fitted to the natural logarithm differenced disease incidence.

<p>Campylobacteriosis SARIMA (1, 0, 0) (2, 0, 0)₁₂ (A-C), salmonellosis SARIMA (1, 0, 0) (1, 0, 0)₁₂ (D-F), cryptosporidiosis SARIMA (1, 0, 0) (1, 0, 0)₁₂ (G-I), giardiasis SARIMA (1, 0, 0) (1, 0, 1)₁₂ (J-L). The x-axis gives the number of lags in months and the grey shaded areas represent the 95% confidence interval.
