Alarms of the top-performing model. True and false alarms for the best performing model, faceted by school year: the seasonal logistic random intercept model using ES-allavg data with l=7, Θ=0.20, interpolated missing values in the training data. Averaged absenteeism is plotted as grey bars, with actual laboratory-confirmed influenza case counts overlaid as black bars, and the epidemic reference day is indicated by the dashed yellow line for each school year
