GEST analysis for Campylobacter cases in England and Wales from 2005 to 2009 using temperature and rainfall as explanatory variables, and seasonal hierarchical clustering. a Cases with the fitted mean decomposed by trend, seasonality, temperature and rainfall; b Fitted linear trend in time; c Fitted seasonality; d Fitted varying coefficients for temperature; e Fitted fixed coefficient for rainfall; f Campylobacter cases; g Sub-regional clustering by seasonality using Ward’s Minimum Variance based on the GEST model. h Seasonal distribution of Campylobacter cases in the three main clusters
