generateItemParameterSample is a function for generating item parameter samples.
Used for the FB (full-Bayesian) estimation method.
generateItemParameterSample(config, item_pool, bayesian_constants)If either the interim or the final theta estimation method is FB,
generateItemParameterSample returns a length-ni list of item parameter matrices, with each matrix having n_sample rows.
Otherwise, the function returns NULL.
a config_Shadow object. Use createShadowTestConfig for this.
an item_pool object. Use loadItemPool for this.
a named list containing Bayesian constants.
