I am fitting a Bradley-Terry model on binary choice data between two pairs of dollar amounts/probabilities. I am currently doing parameter recovery for my risk aversion parameter–r in the model below. Specifically, there are no posterior samples for r \approx 0 but there are samples for |r| > 0.1, t…

Also consider https://cran.r-project.org/package=pcFactorStan

This was user error. I needed to standardize the transformed parameter dist_pwr_util to match the generated data. For future reference here’s a great post on BT Models: https://statmodeling.stat.columbia.edu/2014/07/13/stan-analyzes-world-cup-data/

Have you looked here ? Are you using @Bob_Carpenter’s implementation?
