How the forecast was made
Exponential smoothing15% weekly error, unbiased6% 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 15% on average (27% day by day), and it showed no systematic bias. A same-weekday-last-week guess would have been off by 16%.
actual forecast, 80% and 95% range what the model said during the report card windoweach/day
Projected on hand, each: today's stock plus open orders on their expected dates, minus the forecast, day by day.
