I realize that probably this is one of the most difficult courses in our program (ESS Bocconi). In fact, I invested a big deal of time studying it.
Here you can find some materials I have done while I was following the course of Advanced Statistics with Prof. Marco Bonetti during the fall semester of 2012:
-My handwritten notes (161 MB) taken with Notability on my iPad: Here
-A review of distributions that you should know by heart: Distributions
-A review of the most important formulas that you should know by heart (also): Important Formulas for Statistics
