The Min No Aya Win clinic on the Fond Du Lac reservation has seen a small amount of patients on a daily basis as they prepare for a wave of COVID-19 cases to hit their area. Dr. Vainio MD, a member of the Mille Lacs Band of the Ojibwe tribe has worked at the clinic for decades and has never seen anything like this pandemic. The week of May 4th, he worked the respiratory cases at the clinic. Only one doctor a week takes all the respiratory cases to minimize the amount of people potentially exposed to the virus.

COVID cases are surging in Stearns County, in large part due to three meat packing plants in the area. We photograph St. Cloud Mayor Dave Kleis as he broadcasts his daily COVID-19 update to constituents on Thursday, May 7, 2020 at St. Cloud City Hall in St. Cloud, Minn.

What began in March as a small camp consisting of about a couple dozen homeless adults has now swelled to more than 100 residents in tents. Known as "Camp Quarantine," the fast-growing encampment has raised alarms over the health of the camp residents amid the coronavirus pandemic. Construction crews will begin installing a large metal fence around a homeless camp. Police are also expected to be on site too. The fence is being erected to contain the growth of the sprawling camp, which now has about 100 residents in rows of tents. The camp is located on Met Council property along the light-rail line near E. 28th Street and Hiawatha Avenue.

Stephen Cole, Jennifer Hill, Luke Keele, Ilya Shpitser, and Dylan Small write: We wanted to provide an update on our efforts to build the Society for Causal Inference (SCI). As you may recall, we are creating the SCI as a home for causal inference research that will increase support and knowledge sharing both within the […]

Will Marble writes: I’m a Ph.D. student in political science at Stanford. Along with colleagues from the Stanford medical school, law school, and elsewhere, we recently completed a white paper evaluating the evidence for and tradeoffs involved with shelter-in-place policies. To our knowledge, our paper contains the widest review of the relevant covid-19 research. It […]

Josh Rushton writes: I’ve been following your blog for a while and checked in today to see if there was a thread on last week’s big-splash Stanford antibody study (the one with the shocking headline that they got 50 positive results in a “random” sample of 3330 antibody tests, suggesting that nearly 2% of the […]

Lauren and Jonah wrote this case study which shows how to do Mister P in R using Stan. It’s a great case study: it’s not just the code for setting up and fitting the multilevel model, it also discusses the poststratification data, graphical exploration of the inferences, and alternative implementations of the model. Adam Haber […]

  This post is by Phil Price, not Andrew. I’m going to say right up front that I’m not going to give sources for everything I say here, or indeed for most of it. If you want to know where I get something, please do a web search. If you can’t find a source quickly, […]

Kostya Medvedovsky writes: I wanted to direct your attention to the University of Texas COVID-19 Modeling Consortium’s new projections. They’re very similar to the IMHE model you’ve covered before, and had some calibration issues. However, per the writeup by Spencer Woody et al., they do three things you may be interested in: They fix an […]

Uros Seljak writes: You may be interested in our Gaussian Process counterfactual analysis of Italy mortality data that we just posted. Our results are in a strong disagreement with the Stanford seropositive paper that appeared on Friday. Their work was all over the news, but is completely misleading and needs to be countered: they claim […]

The above line is not a joke. It’s from Buzzfeed. Really. Stephanie Lee interviewed a bunch of people, including me, for this Buzzfeed article, “Two Big Studies Say There Are Way More Coronavirus Infections Than We Think. Scientists Think They’re Wrong.” I liked the article. My favorite part is a quote (not from me) that […]

So, there’s this new study doing the rounds. Some economists decided to study the twitter followers of prominent coronavirus skeptics and fearmongers, and it seems that followers of Nassim Taleb were more likely to shelter in place, and less like to die of coronavirus, than followers of Richard Epstein or Cass Sunstein. And the differences […]

I understand the above quote completely. Life would be so much simpler if my work was just reviewed by my personal friends and by people whose careers are tied to mine. Sure, they’d point out problems, but they’d do it in a nice way, quietly. They’d understand that any mistakes I made would never have […]

The following came in the email: I’m a reporter for **, and am looking for comment on the stats Gov Cuomo just released. Would you be available for a 10-minute phone conversation? Please let me know. Thanks so much, and here’s the info: Here is the relevant part: In New York City, about 21 percent, […]

Jon Baron read the recent article, “Presenting Characteristics, Comorbidities, and Outcomes Among 5700 Patients Hospitalized With COVID-19 in the New York City Area,” and sent the following message to one of the authors: I read with interest your article in JAMA. I have been trying to follow this issue closely, if only because my wife […]

The OHDSI study-a-thon group has a pre-print An international characterisation of patients hospitalised with COVID-19 and a comparison with those previously hospitalised with influenza. What is encouraging with this one over yesterday’s study, is multiple data sources and almost too many co-authors to count (take that Nature’s editors). So an opportunity to see the variation […]

Suppose I play EJ in chess—I think his rating is something like 2300 and mine is maybe, I dunno, 1400? Anyway, we play, and my only goal is for the games to last as many moves as possible, and EJ’s goal is to checkmate me in the minimal number of moves. Say I have to […]

The talk will be sometime the morning of Wed 6 May in this seminar. Title: Some statistical issues in the fight against coronavirus. Abstract: To be a good citizen, you sometimes have to be a bit of a scientist. To be a good scientist, you sometimes have to be a bit of a statistician. And […]

The other day I wrote about the challenge in addressing the pandemic—a worldwide science/engineering problem—using our existing science and engineering infrastructure, which is some mix of government labs and regulatory agencies, private mega-companies, smaller companies, university researchers, and media entities and rich people who can direct attention and resources. The current system might be the […]

Seth Flaxman et al. have an updated version of their model of coronavirus progression. Flaxman writes: Countries with successful control strategies (for example, Greece) never got above small numbers thanks to early, drastic action. Or put another way: if we did China and showed % of population infected (or death rate), we’d erroneously conclude that […]

I’ve been reading a couple of old books of book reviews by Anthony Burgess. Lots of great stuff. He’s a sort of Chesterton with a conscience, for example in this appreciation of Uncle Tom’s Cabin: As for Tom’s forgiving Christianity—‘O, Mas’r! don’t bring this great sin on your soul! It will hurt you more than […]

I originally gave this post the title, “Stigler: The Changing History of Robustness,” but then I was afraid nobody would read it. In the current environment of Move Fast and Break Things, not so many people care about robustness. Also, the widespread use of robustness checks to paper over brittle conclusions has given robustness a […]

Kevin Lewis pointed me to this article. It seemed kinda familiar, I took a look at the abstract, and I realized . . . I reviewed this article for the journal! Here was my referee report: The paper seems fine to me. I have only two minor comments, both relating to the abstract. 1. I […]

The other day we posted some Stan models of coronavirus infection rate from the Stanford study in Santa Clara county. The Bayesian setup worked well because it allowed us to directly incorporate uncertainty in the specificity, sensitivity, and underlying infection rate. Mitzi Morris put all this in a Google Collab notebook so you can run […]

See here. Please share your reactions and suggestions in comments. I’ll be talking with Seth Flaxman tomorrow, and we’d appreciate all your criticisms and suggestions. All this is important not just for Italy but for making sensible models to inform policy all over the world, including here.

What’s new? The new and shiny reduce_sum facility released with Stan 2.23 is far more user-friendly and makes it easier to scale Stan programs with more CPU cores than it was before. While Stan is awesome for writing models, as the size of the data or complexity of the model increases it can become impractical […]

The University of Washington in Seattle is a big place. It includes the Institute for Health Metrics and Evaluation (IHME), which has produced a widely-circulated and widely-criticized coronavirus model. As we’ve discussed, the IHME model is essentially a curve-fitting exercise that makes projections using the second derivative of the time trend on the log scale. […]

Robin Lee writes: To check for linearity and homoscedasticity, we are taught to plot residuals against y fitted value in many statistics classes. However, plotting residuals against y fitted value has always been a confusing practice that I know that I should use but can’t quite explain why. It is not until this week I […]

By default, ggplot expands the space above and below the x-axis (and to the left and right of the y-axis). Andrew has made it pretty clear that he thinks the x axis should be drawn at y = 0. To remove the extra space around the axes when you have continuous (not discrete or log […]

John Fund writes: [Imperial College epidemiologist Neil] Ferguson was behind the disputed research that sparked the mass culling of eleven million sheep and cattle during the 2001 outbreak of foot-and-mouth disease. He also predicted that up to 150,000 people could die. There were fewer than 200 deaths. . . . In 2002, Ferguson predicted that […]

After getting 80 zillion comments on that last post with all that political content, I wanted to share something that’s purely technical. It’s something Bob Carpenter wrote in a conversation regarding implementing algorithms in Stan: One thing we are doing is having the matrix library return more expression templates rather than copying on return as […]

Ivan Oransky points us to this amusing retraction of a meta-analysis. The problem: “Standard errors were used instead of standard deviations when using data from one of the studies”! Actually, I saw something similar happen in a consulting case once. The other side had a report with estimates and standard errors . . . the […]

Proposal to temporarily loosen restrictions on on-site sales faces uncertain prospect in session's final days.

After closing amid the coronavirus pandemic, the National Park Service is testing public access at several parks across the nation, including two in Utah, with limited offerings and services. Visitor centers and campgrounds remain largely shuttered at Bryce Canyon and Capitol Reef, but visitors are welcome at some of the sites.

Two legislative stalwarts lose endorsements as a wave of younger, more liberal challengers emerges in Minneapolis.

The decision to shelve detailed advice from the nation's top disease control experts for reopening communities during the coronavirus pandemic came from the highest levels of the White House, according to internal government e-mails.

As heads of state, local leaders, business owners and individual citizens weighed the costs of re-opening the global economy, fears of new outbreaks grew. A central question emerged: How much infection and loss of life will emerge amid the push to restart business?

Returning Internal Revenue Service workers in Kansas City are being directed to a room well-stocked with face masks, while some other IRS offices were still telling staffers to buy or make their own as the Trump administration starts rolling out a location-based plan for returning more of the some 2 million federal workers to job sites.

After snapping up more than $500 billion in emergency loans in just three weeks, small-business owners have lost interest in the federal Paycheck Protection Program. Minnesota business owners are among those who may give back a chunk of their forgivable loans.

Companies are rushing to readjust their office designs as they prepare to reopen workplaces amid the pandemic. Strategists and designers are putting aside past concerns about branding and flashy office amenities to focus on employee safety.

It's understandable for anyone near retirement to feel extra anxious. Just remember your best interests.
