I am interested in using shinystan and related visualization tools for MCMC chains generated from custom code (i.e., not from a standard MCMC DSL).
Given that shinystan seems to support multiple backends, I suspect this is possible. Are there any complete examples of how to do this? Is there a simple text-based file format that we could generate which would make this especially easy to do?
For example, if we had a CSV file such as:
iteration, chain, variable_1, variable_2 1, 1, 0.37, 0.28 2, 1, 0.55, 0.33 1, 2, 0.55, 0.282
Then is that enough for shinystan or Plotting for Bayesian Models • bayesplot to use? If so, are there examples of that?
