Hello everyone,
I hope you are doing well. I am currently working on a research project where I'm using the Graded Item Response Theory (IRT) model in Stata16 to analyze survey data. As part of my analysis, I would like to explore the possibility of incorporating the local independency assumption into the Graded IRT model.
Specifically, I am interested in investigating whether there is a way to account for local independency in Stata16 while estimating the Graded IRT model. I have reviewed the Stata documentation and explored some related packages, but I couldn't find clear guidance on this particular aspect.
My question is, how can I apply the local independency assumption to my Graded IRT model in Stata? Are there specific commands, options, or additional packages that I should consider? If anyone could provide some guidance, code examples, or point me to relevant resources, I would greatly appreciate it.
Thank you in advance for your time and assistance.
Best regards,
Maryam
