In edstan: Stan Models for Item Response Theory

Stan for item response theory

Description

edstan Streamlines the fitting of common Bayesian item response models using Stan.

Details

A typical workflow in fitting a model using edstan involves the following sequence:

1. irt_data to format the data,

2. irt_stan to fit a model,

3. stan_columns_plot to view sampling diagnostics, and

4. print_irt_stan to view parameter summaries.

The package includes six Stan item response models (see irt_stan for a list) and two example datasets (aggression and spelling). It is expected that once that a user is comfortable utilizing the preceding workflow with the predefined edstan models, they will go on to write their own Stan models.
