Last Week ILI rate prediction for HHS regions 6–10 from influenza seasons 2004–2005 to 2012–2013.

Note: 1) Auto-regressive integrated moving average (ARIMA [p, d, q]) method, in which p represents the number of auto-regressive terms, d is the number of non-seasonal differences, and q is the number of lagged forecast errors in the prediction equation; 2) 95% prediction intervals were calculated by bootstrapping the model error 5,000 times; 3) the point estimate and prediction interval were bolded if the observed ILIs rate were not covered by the 95% prediction interval; and 4) last week is defined as week 53 for influenza season 2008–2009 and week 52 for other influenza seasons.Last Week ILI rate prediction for HHS regions 6–10 from influenza seasons 2004–2005 to 2012–2013.
