Here are some commonly used Excel Add-ins for this course. I will let you know what to do with these after the course begins.
Tree Plan
Tree Plan is a utility to create decision trees in Excel.
Megastat (Optional)
Megastat is a statistics add-in, similar to the Data Analysis Toolpak, but with more statistical features. In certain topics, I will show you what a product like this can do, so I provide you the ability to download and install this product if you wish to do so.
