Decomposes a weekly 30-day summary trend into weekly detail trend.
Applicable Scenarios and Problems
Given a trend line of the 30-day sum of sales on a weekly basis, you can use this to reverse-engineer the numbers back into what the actual sales were week-to-week. Note, because the problem is mathematically unsolvable, what is returned are best guess estimates.
