I try to describe Multidimensional Within-Item Partial Credit Model (the text of this model and a part of the data file in the attachments).

So I need to get the theta estimation, but I don't see this estimation in the report-file. I think that I do someting wrong describing the model. Can you hint me where mistakes are?

Also, do you know where I can find out the likelihood function of the model in the attachments (file - model.jpg) and how ConQuest estimate the latent parameters mathematicly?
