Thanks for this great resource! In the section on Pearson Correlation, what is rank(x)? Did I miss it? If not, I suggest to elaborate on this in the text as I am probably not the only one with this question. Awesome work!

Great idea/catch. Will do that, or at least link to a pedagogical resource. I'm hoping to do it before the weekend is over.

I just added some theory on ranks. Let me know what you think.
