恩，提示了：Minimization was unsuccessful
The results that follow are therefore incorrect.
The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 2 additional constraints.
但是按照识别规则，自由度应该够了,
Computation of degrees of freedom (Default model)
Number of distinct sample moments: 21
Number of distinct parameters to be estimated: 15
Degrees of freedom (21 - 15): 6
这是什么原因，和我的数据有问题？ |
