Stan Weekly Roundup, 22 September 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…

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…

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…

mc-stan.org down again (and up again)

[update: back up again 20 minutes later. sorry for all the churn and sorry again it went down.] My fault again. Really sorry about this. I’m actually on a real vacation for the first time in two years and not checking my email regularly and not checking my junk email at all. This time, PairNic […] The post mc-stan.org down again (and up again) appeared first on Statistical Modeling, Causal…

Stan Weekly Roundup, 25 August 2017

This week, the entire Columbia portion of the Stan team is out of the office and we didn’t have an in-person/online meeting this Thursday. Mitzi and I are on vacation, and everyone else is either teaching, TA-ing, or attending the Stan course. Luckily for this report, there’s been some great activity out of the meeting […] The post Stan Weekly Roundup, 25 August 2017 appeared first on Statistical Modeling, Causal…

Summer? What summer? Stan 2.17 is coming and there’s work to be done. Sebastian Weber has been making huge strides in adding MPI parallel autodiff to the math library (with design maturing for Stan itself and the library interfaces). Ongoing discusions on the Discourse forum and prototypes for a function to add to the Stan […] The post Stan Weekly Roundup, 18 August 2017 appeared first on Statistical Modeling, Causal…

mc-stan.org down & single points of failure

August 16, 2017

[update: back up. whew. back to our regularly scheduled programming.] [update: just talked to our registrar on the phone and they say it’ll probably take an hour or two for the DNS to catch up again, but then everything should be OK. I would highly recommend PairNIC—their support was awesome.] mc-stan.org is down because I […] The post mc-stan.org down & single points of failure appeared first on Statistical Modeling,…

This week, more Stan! Charles Margossian is rock star of the week, finishing off the algebraic solver math library fixture and getting all plumbed through Stan and documented. Now you can solve nonlinear sets of equations and get derivatives with the implicit function theorem all as part of defining your log density. There is a […] The post Stan Weekly Roundup, 11 August 2017 appeared first on Statistical Modeling, Causal…
