Extract Posterior Draws as a Matrix

Usage

posterior_draws(model, params = NULL, ...)

Arguments

model: An hbmfit object.
params: Optional character vector of parameter names; NULL (default) returns all parameters.
...: Additional arguments forwarded to as_draws_matrix.

Value

A draws matrix (rows = MCMC iterations, columns = parameters).

Examples

# \donttest{
library(hbsaems)
library(brms)
data("data_fhnorm")
model <- hbm(brms::bf(y ~ x1), data = data_fhnorm,
             re = ~ (1 | regency),    # area-level random effect
             chains = 4, iter = 2000, warmup = 1000,
             cores = 1, seed = 1, refresh = 0)
