  iter = 1000,
  chains = 2,
  existing_model = NULL
)

Arguments

data

Data frame for model fitting.

model_formulas

Named list of formula strings to compare.

family

Model family (default "gaussian").

iter

Number of sampling iterations.

chains

Number of MCMC chains.

existing_model

An existing brmsfit object to include in comparison.

Value

A list with LOO comparison table, fitted models, and LOO objects, or NULL if fewer than two models succeed.

Examples

dat <- simulate_scd_data()
run_model_comparison(dat, build_comparison_models("outcome", "phase", "case"))
}
