G. Implementation of MLE Under Nominal Response Scoring

As was the case with the graded response implementation of Appendix F, the estimation of the parameters of an item and an examinee's ability will be treated separately. Not embedding them within the joint maximum likelihood estimation paradigm will reduce the size of the program. The implementation of the maximum likelihood estimation of the item parameters will be provided in Section G.2, and the implementation of the maximum likelihood estimation of an examinee's ability in Section G.3.
