Identify_Q

Matlab code for checking identifiability conditions and performing simulation studies for our paper Sufficient and Necessary Conditions for the Identifiability of the Q-matrix, Yuqi Gu and Gongjun Xu (2019+), accepted by Statistica Sinica.

1. Folder "check_conditions" for checking the proposed identifiability conditions:

   check_conditions_main.m (main file including several examples)

   check_Theorem1.m

   check_Theorem2.m

   check_Theorem3.m

   check_Theorem4.m

   check_generic_complete.m (for checking Theorem 5)

2. Folder "simulations" for performing simulation studies including:

   simulations in Section 3.1 in the main text;

   simulation studies I-VII in the Supplementary Material.
