Resources

Recommended books are given in the lecture notes.

Previous years' lecture notes are available, along with slides from 2021, 2020, 2018 and 2017 (also with 4-up versions) for those who want to look ahead. Most of the course is the same; the main changes are that graphical lasso has been removed, and the trek rule, optimal adjustment and the forbidden projection method have been added.

Steffen Lauritzen taught an earlier incarnation of this course, and his notes might be useful.
