           New blog: If you use observation-level random effects, your predictive checks are probably wrong. Here's how to do it the right way in both #brms and #PyMC tl;dr: you need to sample new levels of the OLRE to avoid a false goodness-of-fit  https://t.co/sPD1wl8cnO

             It feels like whenever OLS comes up on this site, one camp is talking about model checking (residuals, predictive plots) and the other about standard errors. Both talk past each other. Onlooks become more confused.

             Mi gente! I'm thrilled to share the first preprint from the Period Biology Study I've started at Dartmouth! Led by amazing PhD student Irma Vlasac, we lay the groundwork for validating self-collected menstrual samples for DNA methylation research.  https://t.co/3Ro0l28mHC

             More evidence of the prior recession. In the old days a high school graduate could afford a fat-tailed, Cauchy(0, 5) prior on a fixed effect. Now they struggle to afford rent on a N(0, 0.5). @rlmcelreath
