One of the more concerning aspects of this is how long it will take for the new ballroom to be usable and what that says about how long Trump plans to be able to use it

Robustness is better assessed with a few thoughtful models than with billions of regressions | PNAS Robustness is better assessed with a few thoughtful models than with billions of regressions

Great piece on the absurdity of brute force multiverse analyses.

Chris Murphy: "There's a lot of history that has taken place in the East Wing & it was just destroyed without any conversation in the public, without any consent of Congress. It's absolutely illegal. That visual is powerful b/c you're watching destruction of the rule of law as those walls come down"

Just published in Frontiers in Health Services: we provide some validation evidence for a health related social needs screener in Jefferson Health. H/T to my colleague Sara Beachy for the clever use of latent class analysis #stats

Most of the clinical prediction model literature seems to align with substantive expertise and correct model identification, and I believe there’s much more fruit to bear in this approach than in data mining AI pipelines

Tl:dr I’m still not convinced that engineering solutions to I’ll-defined prediction problems are the way we should be going in quantitative health research

So sure, you can get 1,000,000 β€œtraining examples” where say 10% are readmissions, but what are the key β€œfeatures” for this problem? Should we simply pour it into an automated fitting procedure or do we get more out of simpler models with built with substantive insight on the causes of readmission?

Contrast that with trying to predict whether a patient will experience an unplanned readmission to the hospital in, say, 90 days from an index admission. If you ask physicians and nurses from 10 different specialties, you’ll likely get 10 different problem definitions.

I’ve been reading some old neural networks texts and one thing that strikes me is the vast difference between a problem like optical character recognition and that of clinical prediction models. The former problem being relatively well-defined with synthetic examples easily produced.

Anyway Hakeem Jeffries and Chuck Schumer are both New Yorkers and the top Democrats in the House and Senate, respectively, and any point they could learn how to use a shutdown to make the point that we’re living in fascism.

They can keep holding press conferences in the Senate studio like every other press conference before it, talking to the same reporters, pretending like we live in a redeemable timeline where if they just keep on acting like it’s 2007, we might fall through a time portal that makes it so. But we live here in a country with a co-opted executive branch led by racist, xenophobic idiots who do not believe in law, empowered by a slavishly devoted Supreme Court that has decided shoveling unlimited power to said executive is more important than the law it disregards, and where the president thinks he can send national guardsmen from red states to blue states just because people of color live here and Fox News hosts hate that.

Remember folks. The original bluesky ethos by us bluesky elders (apparently I count?) is block and move on.

Don't quote dunk, don't pick fights.
Block, and move on.

This is what made this site unpalatable to the right early on, and we can continue to make it unpalatable to them.

Same thing is happening to Cross Validated, the StackExchange stats site, which I’m pretty sure has contributed to LLMs. Traffic and activity is way down, but often there are new questions like β€œI asked chatGPT … but I’m still not sure” ☹️

Trump found another $20 BILLION to give to Argentina, totaling their bailout to $40 BILLION.

Yet we can’t afford to prevent millions of Americans from losing their healthcare.

Shame.
