stanfit objects and returns a
consolidated stanfit object. The stanfit objects to be merged
need to have the same configuration of iteration, warmup, and thin, besides
being from the same model. This could facilitate some parallel usage of RStan.
For example, if we call stan by parallel and it returns a list of
stanfit objects, this function can be used to create one stanfit
object from the list.sflist2stanfit(sflist)stanfit objects.stanfit consolidated from all the input stanfit
objects.stan
