Projections for 3 months of future sales for each location

[killerinstincti]

I am having difficulty with this project. I am trying to run a linear regression to predict 3 months of future sales for the data set attached. I can not figure out what is supposed to go where in order for it to run correctly. Thank you in advance for any assistance.

Many people here will not download attachments. Better you should include (a portion of) the data in your message itself, as a SAS data step.

Nevertheless, we still can't help you unless you explain more about this regression, and show us the code you have tried already by pasting it into the box that appears when you click on the little running man icon.

Since this seems to be a forecasting issue: do you have SAS/ETS licensed? Run PROC SETINIT to determine this.
