sim_CRUM_N1000: Simulated observed response data, Q-matrix and model...

In dcminfo: Information Matrix for Diagnostic Classification Models

Description

Artificial Q-matrix for 14 items with 3 attributes. A list of observed response data for 14 items, that was generated using the compensatory reparameterized unified model (C-RUM; Hartz, 2002).

Usage
