@allanmjoseph.bsky.social has been telling me there needs to be a "Dartmouth Atlas, but for pediatrics" for maybe a literal decade? And now there is!

I believe it’s used all the time in epi / public health for binary outcomes! Coefficients have a nice interpretation as relative risk ratios. And often used for estimating vaccine effectiveness, like in the RCT of the Novavax vaccine for Covid: www.nejm.org/doi/full/10....
Safety and Efficacy of NVX-CoV2373 Covid-19 Vaccine | NEJM

This rules!! Just FYI there is a minor typo on the Scheduling page ("Both Intercity and Commuter trains are scheudled every 15 minutes at consistent and predictable intervals.")

Just don't run predictive margins!! They are not the same!

Toying around with this yesterday in Stata, clogit, xtpoisson, and ppmlhdfe were pretty similar in speed. But I just had one level of fixed effects (the group id). I would bet if you have additional fixed effects in the regression ppmlhdfe is far superior.

Fun fact: you can estimate a conditional logit by running a fixed effects Poisson. They yield the same estimates and standard errors - they maximize the same likelihood. Poisson regression forever!

@instrumenthull.bsky.social where are we on this?

lol he is???

Also hopefully not a β€œDoctor Mike Reacts to Confused Health Economist” video situation

Not everyone in the US knows each other Rafe!!

Only in the sense that the algorithm is pushing me his entire repertoire

As someone on the Pitt to ER pipeline I strongly recommend this (now burning through ER season 8)

Doctor Mike!!! Let this be your introduction to the broader Dr Mike commentary universe

I thought I'd put the administration's proposed "compact" with universities in context, so I wrote the blog post below.

It's especially for journalists covering this story!

Many details about how the compact itself works and why the administration has retreated to this strategy.

I think at Mailman at least there is an opportunity to request an extension, it isn't automatic. Just based on an email I saw from earlier this year. I'm not sure how hard it is to actually get the extension

The bus I've been taking this week makes local stops then runs on the highway. Like the bus in the movie Speed. It's all I can think about on my way in.

Yesterday I had the privilege of visiting the Broad Street pump! Sadly, I saw that the pump handle had been removed. I worked to reinstall the pump handle so local residents would not be deprived of this vital resource. So glad to bring some of the latest American public health ingenuity to London!
Statement from the largest economics association about the BLS firing

As context: AEA approximately never makes such public statements

This is a big deal

Congrats Arrianna!!!
News reports say Columbia paid a "fine" of $200 million, which is grossly excessive, given the lack of any government authority to impose such a fine. On the blog, I parse the agreement and the stakes to explain what the dollar figure really reflects and its ominous implications. πŸ‘‡

Yes!!!!!

Great rejoinder to a WSJ letter that (IMO quite incorrectly) interpreted the Oregon Health Insurance Experiment as showing that Medicaid doesn't improve health.

Defenders of Medicaid cuts are misunderstanding a study I worked on
Defenders of Medicaid cuts point to the Oregon Health Insurance Experiment to argue that the cuts won’t harm people’s health. But they misunderstand the results, writes one of the study’s authors.

If you end up using it please let me know how it goes! It seems like the RxNorm data is good for this application but would love confirmation...
