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:
-
irt_data
to format the data, -
irt_stan
to fit a model, -
stan_columns_plot
to view sampling diagnostics, and -
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.
