I've been thinking about some sort of regression syntax in Stan. It's kind of a follow up to [Speeding up hierarchical models](https://discourse.mc-stan.org/t/speeding-up-hierarchical-models/14783). When I say regression syntax I'm talking about...
This is a proposal for a Laplace approximation algorithm to Stan. Rendered output is [here](https://github.com/bbbales2/design-docs/blob/feature/hessians_optimize_cmdstan/designs/0016-laplace_approximation_algorithm.md) Edit: I just totally changed the text here. A lot is changed since this the...
I'm following up on this conversation on Discourse: https://discourse.mc-stan.org/t/process-for-design-docs/ I edited the README.md to reflect a few things: - proposals are welcome from everyone - comments are welcome from everyone...

This is a first draft for Stan's code of Conduct, it's NumFOCUS's CoC with a find and replace for NumFOCUS for Stan. There's a few outstanding points I've marked as...
If we had annotations described in [design doc 33](https://github.com/stan-dev/design-docs/blob/master/designs/0033-declaration-annotations.md) I believe it is a nice solution to allowing users to pick a parameterization of a constraint (if we had it)....
This is ready to review. I tried to flesh out how we'd actually code this and document it in the *Reference Manual*.
