但总会出现:The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 3 additional constraints.的提示,所以到底是哪一步出了问题呢?
先谢谢各位大神!
PS.以下为Notes for Model的所有数据,没有自由度问题 Notes for Model (Default model) Computation of degrees of freedom (Default model)
Number of distinct sample moments:
55
Number of distinct parameters to be estimated:
26
Degrees of freedom (55 - 26):
29
Result (Default model)
The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 3 additional constraints.
