# 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)

print_irt_stan(twopl_fit, spelling_list)
# Or
