The 'thurstonianIRT' package.

Description

This package fits Thurstonian Item Response Theory (IRT) models using 'Stan', 'lavaan', or 'Mplus'. To bring your data into the right format, use the make_TIRT_data function. Models can then be fitted via fit_TIRT_stan, fit_TIRT_lavaan, or fit_TIRT_mplus depending on the desired model fitting engine. Data from Thurstonian IRT models can be simulated via sim_TIRT_data.
