How long before period end a forecast was made; accuracy is only comparable at the same horizon.
Forecast horizon is the weeks between the date a forecast was made and the end of the period it forecasts. Error shrinks as the horizon shortens, so an accuracy figure without its horizon means little. Error at twelve, eight, four and one weeks, from saved snapshots, gives the horizon curve, and the team's own prior curve is the benchmark for the next one.
The weeks between the date a forecast was made and the end of the period it covers.
Errors at twelve, eight, four and one weeks before quarter end were 14, 10, 5 and 2 percent. That curve is the team's own benchmark for next quarter.
Accuracy quoted with no horizon. Ninety-five percent a day before the close is not comparable with anything.
