if you want to know what the full set of initializations chosen for all parameters, you will need to get that information from the stan::services layer - the initialize function takes the user specified values or init radius and creates a stan::io::var_context object with initial values for all model parameters. I don’t think we have a good way of dumping the contents of a var_context object as text - I might be wrong. see https://github.com/stan-dev/stan/blob/ea71828c75ca084fb2e978e57b4d143a39f4a224/src/stan/services/util/initialize.hpp#L69. given this, very much appreciate Aki’s trick.
CmdStan only knows what the user-specified inits are - this information is already reported in the Stan CSV file header comments section.
entirely agree, but the problem needs to be addressed at the stan::io / stan::services layer.
