Fit the restricted pupil time-course model with an approved backend

Source: R/pupil-fit.R
fit_pupil_model_backend.Rd

Fits only a specify_pupil_timecourse_model() specification through brms using full MCMC sampling and either rstan or cmdstanr.

Usage

fit_pupil_model_backend(
  specification,
  backend = c("rstan", "cmdstanr"),
  chains = 4L,
  iter = 2000L,
  warmup = 1000L,
  cores = min(2L, chains),
  seed = 2026,
  adapt_delta = 0.95,
  max_treedepth = 12L,
  refresh = 0L
)

Arguments

specification

Approved pupil model specification.

backend

"rstan" or "cmdstanr".

chains, iter, warmup, cores, seed

Sampling controls. Package-controlled cores are capped at two.

adapt_delta, max_treedepth, refresh

Fixed safe sampling controls.

Value

A gp3bayes_pupil_fit.

Governance boundary

This interface accepts no arbitrary formula, family, Stan program, inference algorithm, or unrestricted backend arguments. A returned fit does not establish convergence, adequacy, predictive validity, or psychological interpretation.
