Create a brms-Based Simulation-Based Calibration Plan — create_brms_sbc

Constructs a complete SBC generator/backend pair using the restricted gp3bayes brms translation. Because the generator and backend share brms implementation code, this plan is mainly a computational-calibration check; custom independent generators remain preferable for detecting shared implementation errors.

Usage

create_brms_sbc_plan(
  specification,
  n_sims = 20L,
  backend = c("rstan", "cmdstanr"),
  chains = 2L,
  iter = 1000L,
  warmup = 500L,
  thin = 1L,
  seed = 1L,
  generator_iter = 3000L,
  generator_warmup = 2000L
)

Arguments

specification: An approved binary or duration specification.
n_sims: Number of simulated datasets.
backend: Either rstan or cmdstanr.
chains: Number of chains used per SBC fit.
iter: Total iterations per SBC fit.
warmup: Warmup iterations.
thin: Thinning interval.
seed: Seed used when datasets are generated.
generator_iter: Total prior-only generator iterations.
generator_warmup: Prior-only generator warmup.

Value

A gp3bayes_sbc_plan.
