Now he’s wrapped in up in a more flexible package {overshiny}, which makes use of Epiverse {epidemics} package and its ability to automatically handle complex social mixing and demographic structure, which in turn is powered by {odin}, allowing users to customise models if needed.

Try it out here:

Want to build an interactive dashboard so others can explore epidemic scenarios? For COVID, @ngdavies.bsky.social spearheaded a great drag-and-drop approach, which made use of the JavaScript-based nature of RShiny... 1/

That was the opening question in the panel at the end!

It's an important distinction, but wouldn't really fall under discussion of drivers of misinformation (i.e. people believing things that are demonstrably false)?

At our recent @lshtm.bsky.social event on misinformation, Chris Whitty gave some useful reflections on common causes and some important considerations for handling it.

Was asked about collinearity again, so here's Vahove's 2019 post on why it isn't a problem that needs a solution. Design the model(s) to answer a formal question and free your mind janhove.github.io/posts/2019-0...

tl;dr

    Collinearity is a form of lack of information that is appropriately reflected in the output of your statistical model.
    When collinearity is associated with interpretational difficulties, these difficulties aren’t caused by the collinearity itself. Rather, they reveal that the model was poorly specified (in that it answers a question different to the one of interest), that the analyst overly focuses on significance rather than estimates and the uncertainty about them or that the analyst took a mental shortcut in interpreting the model that could’ve also led them astray in the absence of collinearity.
    If you do decide to “deal with” collinearity, make sure you can still answer the question of interest.

It's a wonderful historical quirk that a crucial improvement to the greedy algorithm came from Hungary.

I wonder how many people who believed, despite all the available evidence, that vaccines cause autism have now happily switched to believe, despite all the available evidence, that Tylenol/paracetamol causes autism.

Reminds me of Kevin Simler’s piece on ‘crony beliefs’:

I'm giving a free public talk asking 'How certain is certain enough?' at @lshtm.bsky.social on Monday 24th November at 5.30pm, as part of the Global Health Lecture Series. From epidemic response and clinical trials to online misinformation and AI, I'll look at how truth emerges – and why it falters.
How certain is certain enough? | LSHTM
When faced with a new health threat, there are three crucial questions we must consider. What is going on? What can we do about it? And how can we communicate these things effectively? This talk will

Just launched an interactive Bayesian epidemic modelling platform that runs entirely in your browser!

No downloads, no installations, no expensive software licenses. Just open the link and start modelling disease dynamics with real-time parameter estimation.

Please, no more papers with cartoon 'team members' to anthropomorphise slightly different prompts to the same LLM.

Easy version of 9-9-6: Do 12 hours work (or ‘work’), 6 days per week.

Hard version: Your young children only go to bed at 9pm, then they wake up 9 times between them during the night, then are up and ready to go at 6am.

I am (self-evidently) very interested in language. And also in technology. From that perspective, the rise of LLMs has created many new things for me to think about.

One is: why is it that certain very small clusters of words are *clearly written by an LLM*? What is the quality of that writing?

Really enjoyed this piece from @adamjkucharski.bsky.social on the culture war between broad social improvements and targeted scientific understanding as ways to improve health.

It’s frustrating because obviously both are important—but the former is often portrayed as somehow more worthy.

Turns out the rise of germ theory was more complicated than the one liners we usually hear about Snow and Koch ... of course. The travails are interesting and relevant.
