I'll be at New Researchers Conference 2026 this weekend chatting about some recent work on estimating peer effects in noisy networks! arxiv.org/abs/2605.03204

Some LaTeX resources I'd appreciate: - A modern guide to best LaTeX practices - A concise guide to mathematical writing - Typst <-> LaTeX conversion gotchas - Claude skills for all of the above

@grimalkina.bsky.social i love your learning-opportunities claude skill -- do you know of anything similar for web chat interfaces? the web interface is much nicer than clis when discussing math since it renders latex i'm curious about user prompts both for myself and also to suggest to students!

i'm looking for interesting teaching examples where (1) random effects/multilevel models predict better than glmnet (2) glmnet predicts better than random effects #rstats #statistics

We are implementing a similar policy at @arxiv.bsky.social. If there is incontrovertible evidence of LLM slop in a paper, this means the authors did not take the time to read the LLM output and we can't trust anything else in the paper. Penalty is 1 year ban from arXiv followed by...

new print! keith levin and i came with a new approach to estimating peer effects in noisy, low-rank networks i'm very excited about our idea because the approach works with a variety of different noise processes arxiv.org/abs/2605.03204

This is the clearest and most accessible introduction to DML I've ever read: arxiv.org/abs/2504.08324 Congrats to the authors @aahrens.bsky.social, @markeschaffer.bsky.social, et al on this amazing paper and great accompanying R package! I'm now DML-pilled.

what's the recommended workflow for checking the accessibility of a #quarto website? currently i'm setting format: html: axe: output: document in _quarto.yml and checking every page visually and it's not particularly efficient #rstats

We have summer internships y'all! Come work at Posit on the PyData, tidymodels, shiny, or Connect teams: grnh.se/tigz810a3us. You will have an awesome time, learn a ton, and help advance our open source and pro tools 🧰 #rstats #pydata

Claude skills for reviewing manuscripts that I would appreciate: - stylistic advice for math writing (punctuating eqs, etc) - academic tropes (gaps, see quote) and linguistic oddities (gerund form) to avoid - structure of a good abstract/introduction - etc

New on the arxiv: “Graphs are maximally expressive for higher-order interactions” arxiv.org/abs/2602.16937 We clarify central misconceptions in the recent literature on "higher-order networks". w/ @piratepeel.bsky.social , @manlius.bsky.social, and @thilogross.bsky.social Explainer 🧵: 1/N

Graphs are maximally expressive for higher-order interactions

We demonstrate that graph-based models are fully capable of representing higher-order interactions, and have a long history of being used for precisely this purpose. This stands in contrast to a commo...

Is there an #rstats package to visualize how many observations get dropped by each exclusion criteria? Looking for a nice visual way to summarize a sample

New paper! The Linear Representation Hypothesis is a powerful intuition for how language models work, but lacks formalization. We give a mathematical framework in which we can ask and answer a basic question: how many features can be stored under the hypothesis? 🧵 arxiv.org/abs/2602.11246
