How the forecast was made
Exponential smoothing10% weekly error, unbiased70% better than naive
A weighted recent average that learns the weekday pattern and any trend. Recent days count more than old ones.
Report card: the model was fit on history up to Tue Jul 21 and scored on the 56 days after. Weekly totals were off by 10% on average (36% day by day), and it showed no systematic bias. A same-weekday-last-week guess would have been off by 34%.
