@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

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

A new release of the mgcv #RStats 📦 is out on CRAN and Simon Wood (U Edinburgh) has added some significant new features despite the small bump in version number: 🌟 scasm() for estimating GAMs with shape constrained smooths. Can be used with any family & smoothness selection is via the EFS method

Now I'm also looking for a research software engineer to implement a pile of research results to R packages loo, posterior, bayesplot, projpred, priorsense, brms or/and Python packages ArviZ, Bambi and Kulprit. Apply by email with no specific deadline (see contact info at users.aalto.fi/~ave/)

this thread nicely describes the epistemology of a decent portion of modern meta-science, and i think also explains why it lost steam

I missed that an expanded version of Philip Stark's "Pay No Attention to the Model Behind the Curtain" was published a few years back Needless to say it's very good and worth a read link.springer.com/10.1007/s000...

This may just be the best CS paper I’ve read this year. Just read the abstract and first para of the intro! The rest of the intro is really wild too, but very very good: dl.acm.org/doi/pdf/10.1...

Just read a referee report clearly generated by AI and I really hope journals start requiring Gen AI disclosures in referee reports

I was loving Claude Code... until I tried it with #rstats. Constant errors, wouldn't use the tidyverse even when asked, "optimized" functions were slower. Frustrated, I started a session just to teach R to Claude and summarize what it learned into a CLAUDE.md file gist.github.com/sj-io/3828d6...

nice guide to making github profiles (especially academic ones) legible to others!

Also, we think people should stop using forensic meta-analytic techniques that have not been adequately vetted by experts in statistics. The p curve papers have very little statistical detail, and were published in psych journals. They did not get scrutiny appropriate to their popularity. 15/?

This workshop is going to be great fun, and I really look forward to meeting everyone! It would mean a lot to me if you signed up!

Technical writing is hard bcs "writing is thinking" but we often should tell our story not in the order we worked. Solution? I wrote a quick post on how @quarto.org 's embed shortcodes can reframe technical writing as reproducible evidence curation www.emilyriederer.com/post/quarto-... 🧵 (1/n)

I've invested a lot into LaTeX in the last few years and didn't feel a strong desire to pivot, but I just tried @typst.app and I'm an immediate convert The compilation speed is so nice and it's so much easier to understand

The more I do multiverse data analysis, the more I find that conclusions vary dramatically with model specification. This makes me quite hesitant to trust empirical results using network models

Is there a go-to implementation of sparse SVD in #python? scipy.sparse.linalg.svds is much slower than the #rstats counterparts in {irlba} and {RSpectra} and I'm wondering if there are better options (I'm using the same data and CSR representations in both cases)

Hamilton, Tawn, Firth (2023) "The many routes to the ubiquitous Bradley-Terry model": arxiv.org/abs/2312.13619 Very cool! I've considered writing notes on how BT models can be motivated in myriad ways, with diff motivations leading to diff generalizations. This looks like a fantastic crack at that.
