The first "result" is the initial forecast, which can be calculated in many ways and it is usually the first value. See [1] and related links. 2 and 3. Your data is row oriented so you have to set "Group By" to row. The output is always column oriented tough - maybe it should depend on the "Group By" selection. Also note that in Excel's "Damping factor" = (1 - Alpha). When you set "Damping factor" to 0.7 this means Alpha is 0.3; Who knows why they did it this way as it is clearly misleading. Suppressing of column headers is a to-do. [1]: http://en.wikipedia.org/wiki/Exponential_smoothing -- You are receiving this mail because: You are the assignee for the bug.
