Posterior summary of variance components

Reports posterior mean, SD, and credible interval for each random-effect standard deviation (sd_*), each random-effect correlation (cor_*), and each auxiliary distributional parameter (sigma, nu, phi, shape, alpha).

Usage

summarize_variance_components(model, ci_level = 0.95)

Arguments

model

A fitted brmsfit.

ci_level

Credible interval width (default 0.95).

Value

A data frame with columns parameter, type (one of "random_effect_sd", "random_effect_cor", "auxiliary"), mean, sd, lower, upper.

Examples

if (interactive()) {
  dat <- simulate_scd_data()
  fit <- brms::brm(outcome ~ phase + (1 + phase | case),
                   data = dat, refresh = 0)
  summarize_variance_components(fit)
}
