MODFIT for GRM #14

Open glerumd opened 4 months ago

Is there a way to use the GGUM package and/or its included functions (IRT_models, MODFIT) to obtain chi-square singles, doubles, and triples for the GRM?

I think it is possible to adapt it. But, you will have to try it yourself. In doing so, you can see both my code and Drasgow's 1995 paper on this statistic. Good luck
