I know it’s possible to compute generate quantities after sampling using
mod$generate_quantities(). Is there a way to not generate quantities during sampling and only after? Currently, I think I’d need to have two Stan programs, one containing the generated quantities block and one without, to be able to sample without computing all of the GQs during sampling. This isn’t a big deal of course, but I was wondering if there was a way to use one Stan program and then to not compute GQs during sampling.
