Computation of degrees of freedom
Number of distinct sample moments = 153
Number of distinct parameters to be estimated = 37
Degrees of freedom = 153 - 37 = 116
The model is probably unidentified. In order to achieve
identifiability, it will probably be necessary to impose 2
additional constraints.
The (probably) unidentified parameters are marked.
这是怎么回事?该怎么
修改模型啊,
请那位高手指点一二,否则我的
下面工作无法进行了,多谢了!
