are you sure MLR estimation method in MPLUS is the same as MML and FIML in IRT? do you have any reference for this claim?

OK, this is Great. Thanks for your clarification. if MLR=MML so what is the difference between them with FIML method? please let me know.Best Regard

I've never seen them explicitly call it MML, but their description of it is exactly how MML works.In Ch. 8 of their user guide, scroll down to the ESTIMATOR section to find a big table.Notice the asterisk by ML(R/F) under the column when at least 1 variable is categorical, indicating that numerical integration is required (i.e., how MML operates in practice).Terrence D.
