stanfit objectExtract draws from a stanfit object and convert them into lists.
The function rstan::extract() returns the draws for a given parameter as an array. This function
calls rstan::extract() to extract the draws from a stanfit object
and then convert the arrays into lists.
extract_draws(stan_fit, n_samples)A named list of length 2 containing:
beta: a list of length equal to n_samples containing
the draws from the posterior distribution of the regression coefficients.
sigma: a list of length equal to n_samples containing
the draws from the posterior distribution of the covariance matrices. Each element
of the list is a list with length equal to 1 if same_cov = TRUE or equal to the
number of groups if same_cov = FALSE.
A stanfit object.
Number of MCMC draws.
