Q矩阵标定的一种简便方法
A Simple Method to Specify Q Matrix

基于认知诊断的Q矩阵理论,由潜在Q矩阵向量的累赘表达式的分解,给出一种简便的Q矩阵标定方法,并且给出这种方法的证明.
Based on the Q matrix theory,using the decomposing of the redundant expression of a column of the potential Q matrix,it can offered a simple method to calibrate attribute vector,and the method is proved mathematically
