Stan Roundup, 10 November 2017

November 10, 2017

We’re in the heart of the academic season and there’s a lot going on. James Ramsey reported a critical performance regression bug in Stan 2.17 (this affects the latest CmdStan and PyStan, not the latest RStan). Sean Talts and Daniel Lee diagnosed the underlying problem as being with the change from char* to std::string arguments—you […] The post Stan Roundup, 10 November 2017 appeared first on Statistical Modeling, Causal Inference,…

I missed two weeks and haven’t had time to create a dedicated blog for Stan yet, so we’re still here. This is only the update for this week. From now on, I’m going to try to concentrate on things that are done, not just in progress so you can get a better feel for the […] The post Stan Roundup, 27 October 2017 appeared first on Statistical Modeling, Causal Inference,…

Analyzing New Zealand fatal traffic crashes in Stan with added open-access science

October 17, 2017
By

Open-access science I’ll get to the meat of this post in a second, but I just wanted to highlight how the study I’m about to talk about was done in the open and how that helped everyone. Tim Makarios read the study and responded in the blog comments, Hold on. As I first skimmed this […] The post Analyzing New Zealand fatal traffic crashes in Stan with added open-access science…

Halfiax, here we come. I (Bob, not Andrew) am going to be giving a talk on Stan and then Mitzi and I will be teaching a course on Stan after that. The public is invited, though space is limited for the course. Here are details if you happen to be in the Maritime provinces. TALK: […] The post Halifax, NS, Stan talk and course Thu 19 Oct appeared first on…

I missed last week and almost forgot to add this week’s. Jonah Gabry returned from teaching a one-week course for a special EU research institute in Spain. Mitzi Morris has been knocking out bug fixes for the parser and some pull requests to refactor the underlying type inference to clear the way for tuples, sparse […] The post Stan Roundup, 6 October 2017 appeared first on Statistical Modeling, Causal Inference,…

Stan Weekly Roundup, 22 September 2017

September 22, 2017

This week (and a bit from last week) in Stan: Paul-Christian Bürkner‘s paper on brms (a higher-level interface to RStan, which preceded rstanarm and is still widely used and recommended by our own devs) was just published as a JStatSoft article. If you follow the link, the abstract explains what brms does. Ben Goodrich and […] The post Stan Weekly Roundup, 22 September 2017 appeared first on Statistical Modeling, Causal…

Will Stanton hit 61 home runs this season?

[edit: Juho Kokkala corrected my homework. Thanks! I updated the post. Also see some further elaboration in my reply to Andrew’s comment. As Andrew likes to say …] So far, Giancarlo Stanton has hit 56 home runs in 555 at bats over 149 games. Miami has 10 games left to play. What’s the chance he’ll […] The post Will Stanton hit 61 home runs this season? appeared first on Statistical…

Call for papers: Probabilistic Programming Languages, Semantics, and Systems (PPS 2018)

September 20, 2017

I’m on the program committee and they say they’re looking to broaden their horizons this year to include systems like Stan. The workshop is part of POPL, the big programming language theory conference. Here’s the official link PPS 2018 home page Call for extended abstracts (2 pages) The submissions are two-page extended abstracts and the […] The post Call for papers: Probabilistic Programming Languages, Semantics, and Systems (PPS 2018) appeared…

Stan Weekly Roundup, 7 September 2017

September 8, 2017

I was out on vacation last week, but now I’m back! While I was gone… Sean Talts released Stan 2.17 (the math library, the core Stan library, and CmdStan 2.17). RStan and PyStan are in the works. Stan 2.17 will be the last pure C++03 release, that opens up pretty much all of C++11 and […] The post Stan Weekly Roundup, 7 September 2017 appeared first on Statistical Modeling, Causal…

The fundamental abstractions underlying BUGS and Stan as probabilistic programming languages

September 7, 2017
By

Probabilistic programming languages I think of BUGS and Stan as probabilistic programming languages because their variables may be used to denote random variables, with function application doing the right thing in terms of propagating randomness (usually encoding uncertainty in a Bayesian setting). They are not probabilistic programming languages that provide an object language for inference; […] The post The fundamental abstractions underlying BUGS and Stan as probabilistic programming languages appeared…
