  3. Bayesian priors aren't just arbitrary guesses - you can (and should) validate them. Our paper shows how to use prior predictive checks to map your domain knowledge onto the model, ensuring your assumptions generate realistic, well-calibrated priors. #Rstats #Stan #Bayes

  5. Alright, future engineers!
    **Conditional Probability:** P(A|B) is the prob of event A, given event B has already happened.
    Ex: P(A|B) = P(A & B) / P(B). Think: Prob of engine failure *given* low oil pressure.
    Pro-Tip: Essential for Bayesian inference & diagnostics!

  10. Hehehehe, we got another reviewer confused by our use of a 89% credible interval.
    Cue the beauty of prime numbers! And it is my co-author's birth year, I am so happy that I can put this in the answer 😅!

  12. Returning to Bayesian computation now after some time away, I was delighted to see active work on JAGS 5.0!

  14. 🤔 Ah, yet another "innovative" tool promising to fix your #non-deterministic #bugs by throwing #Bayes at #Git like it's some kind of magic wand. 🔮 Because clearly, what we all need in our #debugging toolbox is more statistical hand-waving and fewer #practical #solutions. 😂

  16. You're probably familiar with git bisect, which lets you find a commit that introduces a change in behavior via binary search (`git bisect`). But what if the change in behavior is non-deterministic?

    `git bayesect` is a generalization of git bisect that uses Bayesian inference to solve this problem. If your code has started gaslighting you, give it a try!

  18. 🖤💙 Oh, how nice! The International Labour Organization provided the recording of my yesterday's seminar on my new forecasting system for labour market outcomes and my R package bpvars I developed for them! It's all very good 🤍

  20. My friend Jay Wren recommended a book yesterday at lunch:

    "Thinking, Fast and Slow"
    by Daniel Kahneman

    amazon.com/Thinking-Fast-Slow-

    A recommendation from Jay is an insta-buy. I got it as an audio-book (because of my commute).

    It is not **at all** what I was expecting! I guess I thought maybe I was expecting something like a "self-help" book or the like. No. This is **not** a book aimed at a broad audience. This is a book aimed at people who understand (at least a bit about) probability and bias and category theory and ... What I'm saying is: it's not fluff. It's genuine knowledge aimed square at me. Jay's recommendation was on the money.

    I wouldn't hand this to my MIL (it's past her at this point). I wouldn't hand it to my wife (she's certainly smart enough, but I don't think it falls in her circle of interest). I absolutely **would** recommend it to **you**, or to anyone in my circle of friends.

    Go have some fun!

  21. UPDATE: THIS DID NOT CONSISTENTLY WORK--some model objects still corrupted.

    Went through some agony learning saveRDS() does not preserve all parts of a cmdstan_model object. The model information is corrupted upon re-importing it with readRDS(). I have to use the qs_save() from the qs2 📦 for a save that preserves the model info. #rstats #bayes #mcmc

  23. BREAKING: Henceforth, I shall be using a new technique, “division”, to determine how much an item costs per count or unit weight.

    This advance is a radical and exciting departure from the current method, counting on my fingers and toes.

    🤦🏼 🤦🏼 🤦🏼

    These f-ing morons.

    (For those unfamiliar, #Bayes was an 18th c. British #mathematician who developed an equation that has been used for centuries to calculate the probability of an event given what we already know. For example: if you get a medical test with 80% accuracy, and it returns positive, what is the chance you actually have the tested condition? Not 80%, as you may assume. The answer depends on the likelihood of developing that condition in the first place, and then applying the likelihood that the test is correct. Bayes’ theorem is pervasive in #medicine and many other disciplines, and not recently discovered by nut job RFK Jr. and his empty-headed lackeys.)

  25. The free open source programming language #Stan helps me to make sense of data and to quantify uncertainty. The next annual Stan conference (in Uppsala, Sweden) is now open for registration and abstract submissions. #bayes bayes.club/@mcmc_stan/11570105

  27. When I was in high school, my driver’s ed teacher told us about when **he** learned to drive. He was all over the road. His father was teaching him and immediately saw why: the son was looking at the lines to stay between them, the lines he was touching, the close ones. The father told him "you have to look where you’re going … way down the road!"

    I think they were **both** right (and of course, as always, this is not really about driving). You must keep aiming for the end goal, but you will also make constant adjustments (usually small) to get there. Both matter. This is how you solve problems with code. This is also Bayesian thinking.

  29. Is a tossed coin/die actually random, or is it influenced by the initial physical forces that are imparted to it? Is the outcome an indication of your state at the time of the toss, and is any interpretation of that state valid? What is the probability it is?
