Biostatistics/bioinformatics at Charles University, 2nd faculty of Medicine. Bayesian in practice, but not a fan of Bayesian epistemology. Main on fedi: https://bayes.club/@modrak_m Blog: https://martinmodrak.cz

We just updated the preprint (w @paulbuerkner.com) to address some reviewer feedback. Most notably we added a case study where the model space is huge (2^100) and sampled explicitly with JAGS Things still work, though aggregating the results to get something meaningful becomes important. 1/2

Preprint alert: Simulation-based validation of Bayes Factor computation with @paulbuerkner.com and S. Stroppel. We bring lessons learned in SBC to validation of BFs. arxiv.org/abs/2508.11814 The idea is simple: simulate data from the models, fit and see if the inferences are calibrated. 1/10

Thinking about LLMs for programming, I am reminded of "Worst practices should be hard" (https:// haskellforall.com/2016/04/worst-practices-should-be-hard) - most "good practice" for LLMs, I've seen appears to require fighting the tool and the ecosystem, whereas worst practice is almost effortless...

Multiverse analysis, abdication of responsibility and manufacturing of doubt: I have written on some downsides I see with multiverse analysis (which I like in principle): arxiv.org/abs/2607.14623 I was inspired/provoked to write it by @dingdingpeng.the100.ci (thanks!)
