I am wanting to know how to exclude a cell, or cells, from a FORECAST. I'm doing an analysis called a Leave-One-Out analysis. Basically I need to include all cells in a data-set accept for the ones in the same row (ex. =FORECAST(D2,C3:C22,D3:D22). It works easy on the first row, but after that it won't work because I need exclude a cell with other needed cells both above and below the array series. Is there any way to exclude a cell within an array series in a FORECAST?
The forecast function requires a single contiguous range of cells in each argument (of equal size). So I would say no.
I don't know how involved you want to get in this. I could probably write some VBA to assist.
If you want to pursue you can contact me at firstname.lastname@example.org with the particulars. (this isn't a solicitation for money or work).
