I need to skip the steps in iteration for rstan? Is refresh= OK?

fitA = stan(model_code = trialmodelA,
model_name = “Trial modelA”,
data = datt,iter = iters, warmup = burn,
chains = 1, refresh=0)

Hi! I think you’ll get better answers if you write a bit more to describe what it is you want to accomplish exactly, and what problem you are encountering. Right now, it’s kind of hard to understand what you are asking about, to be honest (in this thread as well as in How to skip iteration in samples for rstan. )

This forum is generally very helpful and friendly in my experience, but I think a bit more context in your posts would make it easier to give you useful answers.
