Computation of degrees of freedom (Default model)

Number of distinct sample moments:	276
Number of distinct parameters to be estimated:	53
Degrees of freedom (276 - 53):	223

Result (Default model)
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 3 additional constraints.
在AMOS里，这是输出的结果，是模型设置错误了吗？还是数据有问题？其中有两个潜变量只有一个观测变量。路径图我也给附上，请各位看一下。。多谢多谢。
