In anticipation of Pi Day, I used Claude Code to create fun math visualizations for my kid (and myself!). Here’s Buffon’s Needle for estimating \pi. Enjoy!

We hope to see you in NYC!

We can’t wait to welcome everyone to next year’s RC28 Summer Meeting at NYU in August! @mikehoutnyu.bsky.social

With the Fall 2026 NYC Kindergarten Application now open, I'm reposting a web app we developed a year ago to simulate a child’s admission probability at a target school based on the DOE hexadecimal random number, # of applicants, and the # of non-sibling seats: siwei-cheng.github.io/NYC_kinderga...

Congrats!!

My 5-yo kid crosses out every hypothesis that he believes to be wrong in his book. I only wish I had that kind of boldness in my own work.

Agreed. I think ESL presents a good transition from classic statistical methods to more recent computational methods.

Yes, thanks for noting that! That’s such a fantastic paper and in my view should be added to every reading list on strat, occupations, culture, text analysis, and computational methods.

If by "computational" you mean quant methods that leverage computational advances, I recommend a hidden gem - "Computer Age Statistical Inference" by Efron & Hastie. I'm also teaching basic chapters from "The Elements of Statistical Learning" (Hastie et al) in my grad-level advanced methods class.
