Hi, I'm using (just another Gibbs sampler) and I need to setup a conditional with four conditions.
I don't think JAGS has a powerful ifelse statement to control flow (but I may be wrong). Some people pointed me to the step function but I don't get it 😰

Any idea to write a conditional structure for 4 conditions?? It should be trivial to do!

- There are several language feature depracations that turn to errors. Probably the most widely used is the old array syntax, e.g. `int arr[5];` gives an error. Use `array[5] int arr;` instead. For this version, all the deprecated features in your Stan code can be updated using the autoformatter. with `--canonicalize=deprecations`.

Please help testing the release candidate with your own models!

CmdStan 2.33 release candidate is now available!

Two major new things are
- a new language type tuples, which allows, e.g., `eigendecompose()` to return both vectors and values with one function call

- a new variational inference algorithm Pathfinder (soon available also in interfaces such as CmdStanR)

...It was Fisher who then discredited inverse probability, and because of his influence it remained discredited until the late 20th century, when Fisher's methods were finally recognized to be flawed instead (doi.org/10.1080/00031305.2016. and doi.org/10.1080/00031305.2019. their flaws, though, were known since the 1930s).

For the history from Laplace to Fisher see for instance Dale (archive.org/details/historyofi).

It's sad how important figures in the history of science get forgotten (often together with their insights).

The original piece
lindahall.org/about/news/scien
has some gross historical inaccuracies. After Laplace rediscovered and successfully used inverse probability (jstor.org/stable/41133662), it kept on being used until the beginning of the 1900s, not forgotten as claimed in the piece...

New version of cmdstanr exposes Stan functions and allows you to directly unconstrain parameters (super useful for seeing parameters as the sampler sees them)! A huge win!

Since this is a instance, a little detail here:

I used to get shit for applying probabilistic models. "Why did they do X instead of Y please tell me!" but at least that seems to be on the decline.

This is what I got from for the Theorem.
No clue why the model came up with that but it's beautiful

@smartin2018, did you ever finish the short paper on this, which Sean mentions in the comments of the blog post?

I'm looking for a good GUI tool to model Bayesian belief networks that is also reasonably accessible to beginners. Should run on Windows.

It's for a friend who isn't much into coding and would like to run some litigation decision analysis.

Any favorite tools/suggestions?
