I need to call LINEST in Excel 2011 for Mac, I would say - this was a detective story. My laziness, my curiosity, all was here! I had a homework from university course to use LINEST.
I even stopped trying to do so on MAC, because after googling I could not find any solution how to do it. (I have tried EACH AND EVERY combination of Fn Ctrl Alt Cmd Return!)
Finally, I found a solution here on stack overflow! I want to mention it again, as it was a long time I spent looking for the solution. I have spent 4 days outside of home, to use just windows PC where it is easy as a pie - F2, CTRL+SHIFT+ENTER.
If you want to check if I tell truth - go to HELP in Excel for Mac, type array formula, find LINEST and look at the solution combination!
The solution: select the range, press CONTROL+U and then press ā+RETURN.
