Check advanced pupil priors through prior-only simulation

This optional backend gate samples only from priors using brms. It does not establish model adequacy.

Usage

check_advanced_pupil_prior_predictive(
  specification,
  backend = c("rstan", "cmdstanr"),
  chains = 2L,
  iter = 800L,
  warmup = 400L,
  cores = min(2L, chains),
  seed = 2026
)

Arguments

specification

An advanced specification.

backend

"rstan" or "cmdstanr".

chains, iter, warmup, cores, seed

Sampling controls.

Value

A gp3bayes_pupil_advanced_prior_predictive object.
