Hi! I am grad student currently working on a package that uses Stan under the hood (specifically, CmdStanPy) for modeling. Ofcourse the package does more things, but Stan and the Bayesian workflow are its core components. I was thinking of including ‘Stan’ as a prefix to my package name. I have see…

I have now received comments from 2022 SGB, and I’ve seen the github discussion for the PR which did update Stan web page. 2022 SGB did also consult NumFocus which is the actual trademark owner. For completness the current version of About the Stan Project – Stan is Copyright and trademark Copy…

Thank you all for the response! Eagerly waiting to see everyone’s opinion on this. Perhaps it would be appropriate to include a disclaimer indicating that a package or project is derivative and not affiliated with the official Stan team. All similar packages that use Stan under the hood could (shou…

I’m still waiting response from any of the 2022 SGB members who have possible discussed this before. I hope I can get back to you soon.

Thank you so much for the clarification!
