Description
The main function of the advanced user interface (API) for wizirt. Must be used in conjunction with fit_wizirt to estimate the model.
Usage
1
Arguments
mode
Must be 'regression' for item response theory. A future version will add 'classification' for latent class analysis.
item_type
The type of IRT model to be run. A character vector of either 'Rasch' or '2PL'.
irt_pars
Logical. Should the parameters be traditional IRT parameterization?
Value
An object to be passed to 'fit_wizirt'.
Examples
1

3
my_model <- irt(item_type = 'Rasch') %>%
set_engine("ltm") %>%
fit_wizirt(data = responses)
