First off thanks for the work and packaging it all up.
The manual (https://cran.r-project.org/web/packages/pcFactorStan/vignettes/brief-manual.html) looks like a nice writeup of how to use the package.
We need to make a decision regarding package contributions to case studies. You are correct that EdStan is in there so why not?
We will be discussing this at this Thursday’s Stan meeting 11am EDT. I’ll get back after then. You are welcome to attend, link to meeting at Stan General Thursday Meeting, June 20, 2019 11 am EDT
