IRT a and b parameters in the Graded Response Model (Samejima, 1969; 1996) are easily derived from Mplus loadings and thresholds.

Is there any way to derive category threshold parameters (c) in the Modified Graded Response Model (Muraki, 1990) in Mplus?

Thank you,
Arjan Berkeljon

I don't know offhand as I am not familiar with the paper. If so, it would be using MODEL CONSTRAINT to define c.
