Overview
- To estimate various CDMs, use GDINA() function
- To extract item and person parameters from GDINA estimates, use coef() and personparm() functions, respectively
- To evaluate absolute model fit, use modelfit() or itemfit() functions
- To evaluate relative model fit, use AIC(), BIC() or deviance() functions
- To validate Q-matrix, use Qval() function
- To detect differential item functioning, use dif() function
- To run graphical user interface, use startGDINA() function
- To simulate data from various CDMs, use simGDINA() function
