Stan 2.14 is out and it fixes the sampler bug in Stan versions 2.10 through 2.13.
Critical update
It’s critical to update to Stan 2.14. See:
The other interfaces will update when you udpate CmdStan.
The process
After Michael Betancourt diagnosed the bug, it didn’t take long for him to generate a test statistic so we can test this going forward, then submit a pull request for the patch and new test. I code reviewed that and made sure a clean check out did the right thing and then we merged. We had a few other fixes in, including one from Mitzi Morris that completed the compound declare define feature. Then Mitzi and Daniel built the releases for the Stan math library, the core Stan C++ library, and then Daniel built the release for CmdStan. After that, Ben Goodrich and Jiqiang Guo worked on updating RStan and Allen Riddell worked through pile of issues for PyStan, and both were released.
Stan Con coming soon!
Over 100 people have registered for the first
It’s at Columbia University in New York on
- 21 January 2017
Andrew Gelman and Michael Betancourt will be speaking, along with nine submitted talks and a closing Q&A panel. Most of the rest of us from Columbia will be there and I believe other dev team members are coming in for the event. There will be courses the two days before.
Hope to see you in New York!
There was some kind of bug in the Mac OS X install through the RStudio command line. I had to restart RStudio manually before I installed. Otherwise I get stuck in a loop where RStudio keeps asking me if it should restart and never gets out of it. But it installed OK once I restarted RStudio.
Could be an RStudio bug. I keep getting these problems while installing other packages via RStudio too.
Never happened to me. Using RStudio Version 1.0.44 .
[Paging the linguist in Bob] Can one say ‘I code reviewed that”?
I don’t know about one, but I say “code reviewed” all the time. The noun “code review” is being verbed, as explained in this explanation of a linguistics-oriented xkcd: https://www.explainxkcd.com/wiki/index.php/1443:_Language_Nerd
I would have at least put a hyphen between code and reviewed. Related: what’s the plural of code? Codes? I keep seeing that and it’s painful to read. “The codes associated with the book are available for download”.
Isn’t “code” non-count in this sense? I would use the plural when “code” refers to a set of numbers (security codes, bank codes, etc.) but not for programming instructions (unless coerced to a count-sense).
Once years ago I was at a talk on natural language processing. A questioner asked about determining the part of speech of a word in a sentence. The speaker was obviously prepared for the question. She replied “It’s well known that in English you can verb any noun.”
And there’s this old chestnut:
Time flies lika an arrow.
Fruit flies like a banana.
Off topic question: Who designed the Stan logo?
Michael Betancourt did the basic design and gave us a bunch of color choices, then Stephanie Mannheim put the finishing touches on it.
Thanks. Very nice.
Could be an RStudio bug. I keep getting these problems while installing other packages via RStudio too. willing to use it and gain the knowledge as much as i can.
