I am considering using Gretl for a Statistics class I teach in an executive MBA program. I am think about this because (i) Gretl is free for students to use, and (ii) it does not require admin rights to install. Point (ii) is the most important. My consern is that while Gretl is great for econometrics, it might require too much techinical skill for an MBA program. Does anyone have any thought and/or suggestions?
