In edstan: Stan Models for Item Response Theory

View a table of selected parameter posteriors after using irt_stan

Description

This function prints a table summarizing the parameters for a fitted edstan model.

Usage

print_irt_stan(fit, data_list = NULL, ...)

Arguments

fit	A stanfit-class object created by irt_stan.
data_list	An optional Stan data list created with irt_data. If provided, the printed posterior summaries for selected parameters are grouped by item. Otherwise, ungrouped results are provided, which may be preferred, for example, for the Rasch or rating scale models.
...	Additional options passed to print.

Examples

# Make a suitable data list:
spelling_list <- irt_data(response_matrix = spelling[, 2:5],
                          covariates = spelling[, "male", drop = FALSE],
                          formula = ~ 1 + male)

## Not run: 
# Fit a latent regression  2PL
twopl_fit <- irt_stan(spelling_list, model = "2pl_latent_reg.stan",
                      iter = 300, chains = 4)

# Get a table summarizing parameter posteriors
print_irt_stan(twopl_fit, spelling_list)

## End(Not run)
