🚨 @rmcelreath.bsky.social @statmodeling.bsky.social & @avehtari.bsky.social are coming on the show mid-June to discuss their new book, Bayesian Workflow!
ONE listener gets to bring a real Bayesian problem onto the recording and have the three of them work through it live.

Fellow probabilistic programmers I came up with a parameterization for a Cholesky factor of correlation matrices that looks good. I'm asking to test and see if it works well for you discourse.mc-stan.org/t/updated-ch...

Hi everyone, I’m asking if people could test out this parameterization of the Cholesky factor of correlation matrices? From my tests on a macpro m1, it looks to be much faster and I can easily sample...

i'm extremely pleased with how well the german version de.pghrt.diy has come together. this was my bottleneck, but now whenever other translators finish i'll be able to have the new translation up within the hour without a hitch. we looooove robust parameterization and localization-agnostic code!!!!

Don't sleep on this.
While we do have some static parameterization for storage location. We don't actually want dynamic parameterization in the cache directive. That would be too early. It should be able to parameterize it using the content of the function and only that.

I think about this a lot — strong parameterization as a way of taking “neutral” OSR and warping it into something else. really interested to see what you come up with in the end.

hmm. I suspect I could get codex to do this, which means I also suspect you could get claude to do this. is your prompting cad-like? parameterization and constraints?

🤷♀️ We have shown that the adjusted parameterization approach improves model accuracy, but does it change model predictions?
Well, predicted herd immunity thresholds are drastically lower under adjusted parameterization!
*Note that this work is not meant to establish real-world vaccination targets.
