Stan Course in Newcastle, United Kingdom!

(this post is by Betancourt) The growth of Stan has afforded the core team many opportunities to give courses, to both industrial and academic audiences and at venues  across the world.  Regrettably we’re not always able to keep up with demand for new courses, especially outside of the United States, due to our already busy schedules. […]

Extended StanCon 2018 Deadline!

(this post is by Betancourt) We received an ensemble of exciting submissions for StanCon2018, but some of our colleagues requested a little bit of extra time to put the finishing touches on their submissions.  Being the generous organizers that we are, we have decided to extend the submission deadline for everyone by two weeks. Contributed submissions […]

The StanCon Cometh

(In a stunning deviation from the norm, this post is not by Andrew or Dan, but Betancourt!) Some important dates for StanCon2018 are rapidly approaching! Contributed submissions are due September 16, 2017 5:00:00 AM GMT. That’s less than 6 days away!  We want to make sure we can review submissions early enough to get responses back […]

Stan/NYC WiMLDS Workshop

On Saturday, July 22nd Mitzi Morris and I (Michael Betancourt) will be hosting a day-long Stan workshop for the NYC Women in Machine Learning & Data Science Meetup Group.  As with most of our workshops the emphasis will be on interactive exercises where everyone builds and running models in Stan.  We’ll start with the foundations […]

StanCon 2018 is live!

This post is by Mike. We had so much fun at StanCon 2017 that we decided to do it again! This year’s conference will take place over three days, from Wednesday January 10, 2018 to Friday January 12, 2018, at the beautiful Asilomar Conference Grounds in Pacific Grove, California.  In addition to talks and open discussion, […]

Working Stiff

After a challenging development process we are happy to announce that Stan finally supports stiff ODE systems, removing one of the key obstacles in fields such as pharmacometrics and ecology.  For the experts, we’ve incorporated CVODE 2.8.2 into Stan and exposed the backward-differentiation formula solver using Newton iterations and a banded Jacobian computed exactly using our autodiff. […]

Stan at JSM2015

In addition to Jigiang’s talk on Stan, 11:25 AM on Wednesday, I’ll also be giving a talk about Hamiltonian Monte Carlo today at 3:20 PM.  Stanimals in attendance can come find me to score a sweet Stan sticker. And everyone should check out Andrew’s breakout performance in “A Stan is Born”. Update: Turns out I missed even […]

Stan at NIPS 2014

For those in Montreal a few of the Stan developers will giving talks at the NIPS workshops this week.  On Saturday at 9 AM I’ll be talking about the theoretical foundations of Hamiltonian Monte Carlo at the Riemannian Geometry workshop ( while Dan will be talking about Stan at the Software Engineering workshop ( Saturday […]

Stan Model of the Week: Hierarchical Modeling of Supernovas

The Stan Model of the Week showcases research using Stan to push the limits of applied statistics.  If you have a model that you would like to submit for a future post then send us an email. Our inaugural post comes from Nathan Sanders, a graduate student finishing up his thesis on astrophysics at Harvard. […]
