🔬 Come and study with us! 🧑💻
We* have TWO funded PhD studentships available as part of @NIHRMaudsleyBRC:
🔹 CO4-035: Machine learning approaches to high-dimensional mediation.
🔸 CO4-036: Flexible machine learning models to capture the dynamics of patient outcomes at scale.
* Jointly supervised by myself and @KimberleyGol.
For project details: maudsleybrc.nihr.ac.uk/acade…
For information about eligibility and how to apply: maudsleybrc.nihr.ac.uk/acade…
👋Feel free to get in touch with questions 👋
Deadline: ⏰ 12th March 2023.
I'm on Mastodon at fediscience.org/@ewan.
It's a bit confusing (see fedi.tips) but worth trying.

I'm at #ICTMC2022 with a poster about how to tell if your mediator and outcome are measuring distinct constructs.
I'll be at Poster Session 4 today (15:25 – 15:45).
This was work with @SVitoratou, Trudie Chalder and @KimberleyGol. PDF at tinyurl.com/mediator-in-disg….
Come and see our #ICTMC2022 poster presentations today!
➡️ mediator or outcome? (@ewancarr)
➡️ #estimands and principal stratification (@KimberleyGol)
➡️ biomarker trials (@RTinchTaylor & @DomJStringer)
➡️ causal analysis (@anca_chisster)

We're ready and excited for #ICTMC2022 next week! Come and see the excellent #trialsmethodology research being presented ⬇️ from @KingsIoPPN @KCLCTU @KCTU_MH_Stats @NIHRMaudsleyBRC
🎙️ I spoke at the @HDR_UK National Text Analytics symposium today about our work to evaluate the NEWS2 early warning score for COVID-19.
🛝 Slides are available at tinyurl.com/hdr-news2.
This was work with @BendayanRebecca, @richdobson, @jthteo and many, many others.

NEW UPDATE of our living review on covid-19 prediction models @bmj_latest
TL;DR: 731 models evaluated, with largest majority very poorly developed, validated and reported, but also a few noticeable exceptions
