Estimating the size of a set using cascading exclusion Let $S$ be a finite set, and $X_1,\ldots,X_n$ an i.i.d. uniform sample from $S$. To estimate the size $|S|$, without further structure, one can wait for repeats and use the birthday problem. This requ...

New paper with Sourav Chatterjee and Persi Diaconis: Estimating the size of a set with cascading exclusion, see arxiv.org/abs/2508.05901 and a whole github repo of examples in R spholmes.github.io/SetSize/, thank you #rstats and #quarto.

About a year ago, we cohosted a veridical data science event. This year, QB3-Berkeley is sponsoring Veridical Data Science for Biology, organized by graduate students and postdocs from the Center for Computational Biology at UC Berkeley. 🎟️ Check it out!

Here is a repository with the exercises I use in my data visualization class. We cover ggplot2/shiny and then consider different types of data (network, text, ...) and models (clustering, ...). I've tried to make the problems somewhat realistic. Feel free to reuse! github.com/krisrs1128/d...

@guggfellows.bsky.social I’m deeply honored to be named a 2025 Guggenheim Fellow—especially as part of the Foundation’s historic 100th class. Grateful to be in the company of so many brilliant artists, scholars, and scientists. #guggfellows2025

I enjoyed the chance to (virtually) visit the department! I appreciate all the great questions -- I'd never considered the connections to supervised LDA and neuroimaging. And if anyone wants to try out the package, it's available here: github.com/lasy/alto/

Simulating microbiome data has been on my mind since the PhD, and writing this together with Saritha, @mixomics.org and @jsb-ucla.bsky.social has been amazingly clarifying. Thank you also to participants of the @mig-unimelb.bsky.social workshops for all the valuable discussions! #rstats #microbiome
