Some Italian guy who lives in London and works on statistical methods in clinical trials for a living.
This work was amazingly led by Lana Broer, and here is the paper with the theoretical results it was based on:

A comparison of different population-level summary measures for randomised trials with time-to-event outcomes, with a focus on non-inferiority trials - PubMed
When the hazards are likely to be approximately proportional, reflecting this in the analysis can lead to large gains in power for difference in restricted mean survival time and difference in surviva...

Usually, the life of a methodologist is*:
- Develop fancy method to solve problem;
- Show through simulations that it makes a huge difference;
- Show application in which it makes no difference at all;
So, great for once to see empirical results matching our expectations!

I think what Darren is suggesting is that you open an OnlyFans account, and use it to post exclusively Stata related content. I am sure it will be a huge success!

🤣 Another STaTa prize coming to the CTU soon...!

BTW, reading this list it just occurred to me why so many people think it is called STATA: it's the logo, that clearly has capital Ts in it!
SO perhaps we should really call it STaTa. 😜

Amazing, thanks, I echo Tim's sentiment! :)

Yes, that's why we were thinking to never give any feedback, or to even give reverse feedback, praising errors! :D

I think it has to do with the nature of our assessments. We give 24 hour exams that students do at home. So we have to be creative and find ways to see who really understood and who didn't / is using AI. I am a bit worried about the one it did well, think I will test every time before submitting!

Hi, we just got a similar tutorial accepted for publication on Stats in Med,for the moment you can access the preprint here: arxiv.org/abs/2404.06967
It is not specifically for R but it contains R code. Also, it is for longitudinal data rather than general multilevel, but hopefully might still help!

Multiple imputation for longitudinal data: A tutorial
Longitudinal studies are frequently used in medical research and involve collecting repeated measures on individuals over time. Observations from the same individual are invariably correlated and thus...
