This FREE suite of Excel Add-ins contains a collection of basic and advanced analytic tools I developed over the years for instructional purposes.
I developed KATE, this site and the tutorials as a hobby, and to learn new skills (who said you can't teach an old dog new tricks?!).
You may use it for anything you want (always at your own risk…), keeping in mind it’s original educational purpose
These add-ins are bundled under a single menu under the Excel AddIns tab.
This version of the suite works with Office 2010 or newer, running on a Windows device (PC or laptop).
It might work on a Mac, depending on the Windows emulator (it is known to work with Virtual Box).
It will (may?) work with Office 365, but it has to accept local macros and libraries (they can't be kept in the cloud).
