Please help me, fellow MastoNerds: What is the appropriate statistical distribution for responses to questions in which participants are asked to rank-order groups of stimuli? And how would it be implemented in pymc3/Stan/Turning.jl? Closest thing I can find is the ordered probit model.

Please and thank you 🙏

@tmcurley i wrote a blog post some time ago about modeling rankings with the exploded logit distribution in Stan: https://bruno.nicenboim.me/2021/03/21/a-simple-way-to-model-rankings-with-stan/

@bruno_nicenboim I especially appreciated the last part of your blog post where you discussed how the exploded logit model could potentially be used in cognitive research, which is exactly what I'm doing. Steyvers, Lee, etc. have great papers closely related to the topic, but don't quite describe this exact situation. Hopefully I'll be able to share some results with Mastodon in the near future!

@tmcurley I got to that for a collaboration that never ended up being a paper, I'm glad it was useful, maybe some day I'll write some more about it. In any case feel free to reach out if I can help!
