I'm working on a project related to IRT.
I really want to analyze my data with python. I googled it, but I couldn't find the module I need.
Do you know some great modules that can handle IRT?
Here is the list of what I want to do:
- estimation of the graded response model (GRM)
- equating using the GRM
- estimation of the multi-dimensional GRM
- equation using the multi-dimensional GRM
If there is no module in python, I also want to know the packages of R, STAN, etc.
