I am excited to share the new preprint with @antcalcagni.bsky.social “Towards a Geometric Characterization of Multiverse Analysis” arxiv.org/abs/2607.11345 #Statistics #OpenScience #SensitivityAnalysis 🧵👇

Towards a Geometric Characterization of Multiverse Analysis

Multiverse analysis makes explicit how empirical conclusions depend on alternative, defensible analytical specifications. Standard approaches usually generate the multiverse first and then summarize i...

Interesting! Moving from "*the* model" to "a handful of" to "the space of" strains culture, training, and political assumptions in science and industry but IMHO it's how we can best turn increased computational power into better research. @giovannisaraceno.bsky.social @antcalcagni.bsky.social

Having a visual component when you are teaching a new concept is always something I value. I went back and redid some old diagrams as animations This website has all mp4, gif and code for you to use yourself in slides of websites! emilhvitfeldt.github.io/tidy-animati... #rstats #quarto #dataBS

It was a pleasure to present my current research on cogntive modeling from ideal observer models to deep neural networks at the University of Padua @unipd.bsky.social, hosted by @giovannisaraceno.bsky.social! Lots of great feedback and scientific exchange 🙏 www.stat.unipd.it/sites/stat.u...

Trick to understanding confidence intervals (ci): "Probability is on the method; confidence is in the output." The probability statement about ci's is only true prior to data collection, but that doesn't stop you from being "confident" about your interval. #edusky #statsky #academicChatter #phdchat

🤖Just saw this extremely evocative paper on deep NNs in the Bulletin of the AMS. The idea of *compositional sparsity* seems be very interesting for both theorists and practitioners. Published version: www.ams.org/journals/bul... Open-access version: cbmm.mit.edu/sites/defaul...
