Worked ok for me using Excel 2016.
Make sure you go to File | Options | Add-ins |
Under Manage "Excel Add-ins", <Go ...> make sure you have "Analysis Tookpak - vba" selected.
Or: In the vba editor, you can also go to Tools : Reference, and check "atpvbaen.xls"
Then, this code worked for me: I just used the upper left corner reference for the output.
Sub Demo()
Regress Range("$N$4:$N$18"), Range("$O$4:$O$18"), False, False, 95, Range("$Q$3"), False, False, False, False, , True
End Sub
