I’m taking Aswath Damodaran’s valuation course and before that took his statistics 101 course. He recommends the following:

- StatPlus (Excel addon, Paid)
- Wizard Pro (He likes it for creating delighful pivot tables, Only for Mac though)
- IBM SPSS (Powerful, overkill statistics features, Paid)
- Oracle Crystal Ball (His go-to program for simulations, Paid)

Note that all of his recommendations are paid and I am looking for free recommendations (or low priced ones).

Context: I don’t know what my use case will be of these programs but it would mainly be **2-D or 3-D regresssion** and a **Monte Carlo simulation**. I don’t need many overkill features. I will be using these mainly with Excel but I am also ok with a stand-alone program.

Could anyone give useful recommendations please? Would really appreciate it as I’m just getting my foot to using proper statistics with valuation.

PS: Prof. uses Oracle Crystal Ball many times during his lectures. So I believe an alternative to that would most likely be helpful for me.
