C'est reparti pour une vaste campagne d'affichage pour Shen Yun dans les transports en commun alors au cas où certain·es n'auraient pas eu le mémo, ne donnez pas votre argent aux membres d'une secte, qu'importe s'ils dansent bien dans leurs habits de lumière, il existe d'autres spectacles en France.
Comme le matraquage publicitaire bat son plein sur Internet, à la télévision, au cinéma et dans le métro parisien en cette période de fêtes : petit point sur Shen Yun et sur les raisons pour lesquelles vous devriez dissuader vos aîné·es de prendre des billets pour ce spectacle qui finance une secte.
It was inevitable, wasn't it🙄 Of course the Telegraph would run with something like this👇 So let's remove some of the rose-tinted spectacles and also look at some of that data comparing 1976 with modern heat waves Because the 1976 nostalgia porn is wearing a bit thin at this stage 🧵1/23

Curious to hear from people: it is common in research to give an Amazon voucher to participants (e.g. Delphi surveys). Do you see an ethical issue with it (because, well, it's Amazon) and if so, what could be a more ethical alternative (that can be used from any country)?

New paper from Shaun Seaman and me on how to simulate data from marginal structural models (MSMs) for survival outcomes, including Cox MSMs. This can be useful in simulation studies evaluating causal inference methods that use MSMs. R code provided. onlinelibrary.wiley.com/doi/10.1002/...
Simulating Data From Marginal Structural Models for a Survival Time Outcome
Marginal structural models (MSMs) are often used to estimate causal effects of treatments on survival time outcomes from observational data when time-dependent confounding may be present. They can be...
