Suggestion for extra contents in the TMLE chapter

[osupplisson]

Hello,

First of all, thank you for all your work, it is really an outstanding contribution that helps applied researchers to better understand how to implement TMLE in practice.

I would like to suggest two ideas of extensions for the TMLE chapter that may help me (and probably others) to apply TMLE in different contexts:

• Applying TMLE with multiple treatments: I am referring here to Professor van der Laan's answer on his blog (https://vanderlaan-lab.org/2020/12/03/tmle-for-multi-level-treatments-and-methods-for-sensitivity-analysis/). I felt I understood how I could implement it in practice but an example may help to avoid any unintended mistakes;
• Applying TMLE to (matched) case-control study: Similarly, I went through Professor Sherri's Ph.D. thesis and some articles but any specific example may help to make things clearer;

Once again thanks a lot for your packages/book!
