【求助】在线等！！新手小白求帮忙AMOS识别总是出现问题，而且按照论坛的方法检查了路径系数都设置好了啊
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.
