In some instances, the initial guess for the multi-dimensional estimates is not SPD. This error is because the polychoric correlation contingency table is light on samples. Add a check and...
The Readme file is getting a little long in the tooth. Add some drop-down menus to make it a little easier to read.
I'm not sure if the current implementation will work at scale? I need to do an investigation at the performance. My initial thought is underflow might occur for mml due...
I treat Rasch and 1PL as nested, which means the mml Rasch model assumes a standardized normal population. This is a non-standard way of doing things
Implement the rasch model with ability guessing. This was suggested as alternative to the random guessing usually assumed.
Check compatibility with python 3.10 and setup CI/CD
Current parameter estimation techniques assume order invariance. Investigate discrete state-space parameter recovery of the form θn = A θ n-1 + B μ m = C θn + D μ...
Issues #76 added polytomous ability estimation as an output to most mml methods, would still like a stand-alone function similar for dichotomous methods.

The graded unfolding model is an ideal point IRT model and an extension of the PCM #9. The framework for this model reuses a lot from the partial credit model...
