* EDF is the effective degree of freedom for the estimated smooth terms. Meteorological parameter units: g/kg for specific humidity, mm/day for precipitation, W/m2 for solar radiation.
ǂ Correlation coefficient between the estimated influenza-associated ILI or ARI with the observed during 2010/2011 season.
