Convert to posterior::draws format

Generic function to convert an object to a posterior::draws representation (e.g., draws_array, draws_matrix, or other formats).

Usage

as_draws(x, ...)

# S3 method for class 'rjuliabugs'
as_draws(x, ...)

# S3 method for class 'array'
as_draws(x, ...)

Arguments

x

An object to convert (e.g., a rjuliabugs object or a 3D array).

...

Further arguments passed to specific methods.

Value

A draws object (e.g., draws_array) or a modified rjuliabugs object.

An object of class "rjuliabugs" (a named list) with the following elements:

params

Posterior samples converted to posterior::draws_array.

name

The name of the Julia sampler object (unchanged).

sampler

The sampler object returned by AbstractMCMC.sample in Julia (unchanged).

n_threads

Number of Julia threads detected (unchanged).

mcmc

MCMC configuration parameters; posterior_type is updated to "draws".

control

Control options passed to and used by the sampler (unchanged).

An object of class draws_array (from the posterior package). The 3D array (iterations × chains × parameters) is converted to a draws_array, preserving the chain structure and parameter names.
