Do we still need to test for equal variances before running ANOVA? Probably not as a decision rule. Welch's ANOVA, robust SEs, and variance-modelling approaches handle heterogeneity directly — assumption tests have shifted from gatekeepers to descriptive companions. medium.com/p/do-we-real...

Revised post: Prussian soldiers, horse kicks, and Bayesian inference 🐎 I've revamped an old post on the Gamma-Poisson model — more historical context, a cleaner derivation, and a new section showing how the posterior updates sequentially across 20 years of data. medium.com/p/kicking-it...

Another one from the archives. This was actually the first blog I ever wrote. In it I cover what multicollinearity is and when it becomes an issue for modellers. Enjoy 😊 medium.com/data-science...

This is one from the archives. A while back a provided a discussion about the difference between probability and likelihood. Hopefully it’s still a useful piece for someone out there 🙂 medium.com/data-science...

Hi Bluesky community 👋 I’m a data scientist and mathematical modeller with a background in cognitive science, where I used computational models to study how the brain represents information. Now I build data tools and write about making complex ideas clear and useful. Glad to be here!
