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!

Balkinization: The Art of Replacing the Law with the Deal A group blog on constitutional law, theory, and politics

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.

National Trends in Inpatient Psychiatric Bed Supply, 2011 to 2023 This cross-sectional study discusses trends in inpatient psychiatric bed supplies.

Out today in @jamapsychiatry.com: we find that inpatient psychiatric bed supply increasingly comes from freestanding psychiatric hospitals in large for-profit chains.

Selfie of me smiling in front of the Broad Street pump

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!

AMERICAN ECONOMIC ASSOCIATION
Committee on Economic Statistics and Committee on Government Relations


Statement from the American Economic Association on the
Dismissal of the BLS Commissioner

Leaders of the American Economic Association express their grave concern over the dismissal of the Commissioner of the Bureau of Labor Statistics (BLS) earlier today.
The independence of the federal statistical agencies is essential to the proper functioning of a modern economy. Accurate, timely, and impartial statistics are the foundation upon which households, businesses, and policymakers make critical decisions. Undermining the independence or credibility of these agencies threatens the integrity of the information that markets, institutions, and the public rely on every day.
Measuring the vast and dynamic U.S. economy in real time is inherently challenging. It is standard practice for statistical estimates to be revised as more complete and higher-quality data become available. These revisions reflect the commitment of statistical agencies to accuracy, transparency, and methodological rigor-not failure or bias.
The BLS has long had a well-deserved reputation for professional excellence and nonpartisan integrity.
Safeguarding this tradition is vital for the continued health of the U.S. economy and public trust in our institutions.
We call upon elected officials to respect and preserve the independence of the nation's statistical infrastructure.

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‘‡

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.

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

Trying to identify opioids and other drugs in pharmacy data (claims, PDMP, etc.)? Use my code to quickly build a list of national drug codes (NDCs) using the free public database RxNorm.

I wrote this code to replace the CDC's now-discontinued opioid NDC dataset.
