and Tests (DFIT) analyses. It includes functions to use the Monte Carlo Item
Parameter Replication approach (Oshima, Raju, & Nanda, 2006, <doi:10.1111/j.1745-3984.2006.00001.x>)
for obtaining the associated statistical significance
tests cut-off points. They may also be used for a priori and post-hoc power
calculations (Cervantes, 2017, <doi:10.18637/jss.v076.i05>).
