Dear, I am trying to model the information function of items (and full) based on the continuous response model.
I am using the EstCRM (1.4) package, but it doesn't compute the information function. Another person noticed me of Wang & Zeng's paper (Item parameter estimation for a continuous response model using an EM algorithm, 1998, Applied Psychological Measurement). But I am not sure how to calculate it in R. Please, If someone has calculated that function could you share the script?
