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? Thanks in advance, Cecilia -- Cecilia Reyna Instituto de Investigaciones Psicol?gicas (IIPsi) - CONICET - UNC Facultad de Psicolog?a - Universidad Nacional de C?rdoba (5000) C?rdoba - ARGENTINA Tel. 54-351-5353890 int. 60201 RACC: http://www.revistas.unc.edu.ar/index.php/racc [[alternative HTML version deleted]]

If you haven't already done so, you should probably look here: https://cran.r-project.org/web/views/Psychometrics.html Further detailed discussion of the statistics is generally off topic here. Per the posting guide (linked below): "Questions about statistics: The R mailing lists are primarily intended for questions and discussion about the R software. However, questions about statistical methodology are sometimes posted. If the question is well-asked and of interest to someone on the list, it may elicit an informative up-to-date answer."
