Hello Phil
How can I get empirical item characteristic curves in mirt?
I found this function but it doesn't work: EICC=EmpiricalICCfit(mirt1,1)


How can I overlay an empirical ICC on the model ICC as a graphical inspection of item fit?
Best

Hi Maya,

That is not from the mirt package, so you may have to contact the original package developer for help with this. Cheers.

Phil
