Thank you for all the previous support. I have another question:

I am using eRm to run a partial credit model. Is there a way to ask eRm
to compute and present to me the probability of a person with a specific
ability to achieve each one of the scores 0, 1, 2, 3, or 4 on a specific
question with known step measures (thresholds)? I checked the documentation
but there is no relevant info. (actually, it says that only in the case of the simple Rasch model has the prediction function been written - but again, how are the residuals computed if such a function does not exist?)

 
Thank you for your time
