I keep reading about an Excel Illustrative worksheet that shows how to do alot of the necessary calculations in Excel but have been unable to locate it.  The one link that a user posted no longer works.  Can somebody please lead me to this worksheet?  Thanks.

Thanks as I located the illustrative worksheet.  I have been going through it and cannot find the formulas they used to calculate the autocorrelations.  Just curious if anyone else has been through the worksheet and located them.
