Ideally letters wouldn't be required at all, but I'd settle for them only being required at a much later stage of the process after the first stage of review

I love living in a city full of immigrants and tons and tons of people who are not at all like me and not like each other. It makes us all better and it makes our city better. I know I’m preaching to the choir by saying this on the lib app but I sometimes just get so overwhelmed by how special it is

New preprint out on a way to handle structural and practical violations of the overlap (also known as positivity) assumption in causal inference -- as long as the outcome is bounded, we derive simple partial identification bounds on the ATE. With @alecmcclean.bsky.social and @idiaz.bsky.social

I have a new paper out on a simple way to do causal inference with left-censored outcomes. This comes up with environmental data because measurements often have a lower limit of detection -- e.g. a chemical is undetectable below a certain level www.tandfonline.com/doi/full/10....

Non-parametric treatment effect bounds for left-censored outcomes: estimating the effect of herbicide use on 2,4-D exposure
Causal inference is concerned with defining and estimating the effect of a exposure on an outcome. For example, the Average Treatment Effect (ATE), a causal inference concept, is defined as the pop...

As Netflix’s founder, Reed Hastings, has said, the company’s main competition is sleep; the point is to fill the platform’s library with an endless quantity of easily consumable content.

Márquez may have anticipated even this. In “Solitude,” Rebeca’s arrival brings with it a plague of insomnia that infects the entire town. At first, people are overjoyed to lose “the useless habit of sleeping.” Yet, without access to sleep or dreams, they begin to forget words and memories and basic truths about the world. They mark every object in town, from tables to cows to banana trees, with increasingly detailed signs explaining their names, uses and meanings.

The DHS Program is officially done. As I tell my statistics students, good data is ESSENTIAL to improve the world. We can’t make things better if we don’t know the current state of things. No new DHS data collection is an incalculable loss. www.nytimes.com/2025/02/26/h...

This is a really nice and thought provoking preprint, and I think this point is largely true, and related to how strict causal inference is designed to estimate the effect of causes, but not causes of effects (or "reverse causation" as it's sometimes called www.stat.columbia.edu/~gelman/rese...)

This is an interesting article, and reading it made me wonder what role causal inference has in an alternative epidemiology. Causal inference gives us some nice estimators of e.g. health effects of industrial hog plants on communities, but is that really what is needed, rather than political action?

Nice commentary summarizing some issues with non-parametric Bayes, a big one being that in practice you often end up having to place priors on very abstract objects rather than on the things you may actually have prior information about projecteuclid.org/journals/bay...

New-ish paper alert! arxiv.org/abs/2410.13522   We tackle the challenge of comparing multiple treatments when some subjects have zero prob. of receiving certain treatments. Eg, provider profiling: comparing hospitals (the “treatments”) for patient outcomes. Positivity violations are everywhere.

Fair comparisons of causal parameters with many treatments and positivity violations
Comparing outcomes across treatments is essential in medicine and public policy. To do so, researchers typically estimate a set of parameters, possibly counterfactual, with each targeting a different ...

I started a list of articles, books, and tutorials (with BibTex!) for learning the semi-parametric efficiency theory relevant to causal inference: herbsusmann.com/2024/11/05/r... What have I missed? 🤔
