Good news from #JSM2026: CSCAR@ISR, a statistical and methodological consulting service designed to support faculty, staff, and graduate students, is now officially open for business at the University of Michigan. This is a rebirth of CSCAR, with new features! Visit cscar.isr.umich.edu for details.

It is indeed the people who made this a blast. Thank you @shiraamitchell.bsky.social! And I appreciate your blog posts on survey statistics. I’ve been saving them and have so many comments that I want to share, but I wasn’t sure what I should put under the blog post. We can co-author a book on this.

thank you to Ben Goodrich, @yajuansi.bsky.social, @yulingy.bsky.social, and @charlesm993.bsky.social for organizing !

In NYC celebrating Andrew Gelman’s birthday and honoring his contributions to science: gelman60.com. Day 1 talks covered MRP, MCMC computing, R-hat, regression, missing data, physics, biology, psychology, and education, plus Susan sharing stories from Andrew’s early years as a prodigy and genius.

This is a great honor. I’m truly grateful for the support.
