Hi,
I want to evaluate Rhat for my stanfit using the improved version (reference below). I know that the Rhat is presented when I print the stanfit object, however, I want to know is this the improved version of Rhat?
If not, is there an easy way to calculate it for all of my parameters (i.e. a summary function) rather than having to extract all parameters combine into a matrix and then use rstan::Rhat?
Many thanks,
Philip
