Regression with Microdata
This is an introductory econometrics course that uses Monte Carlo simulation in Excel to teach core regression concepts. I taught a course like this for many years and I used the latest, best version of my course to write a book. I affirm that no AI was used to write any of the text or produce any of the examples.

The latest version of the FRED add-in is available in the Microsoft App Store (from Excel 2019+, Insert --> Get Add-ins). I continue to use the older version that I call Legacy FRED. Although it is no longer supported, it still works with Excel versions from Excel97 and greater. It can be freely downloaded from the link above and installed with Excel's Add-ins Manager.
