Notes for Model (Default model)
Computation of degrees of freedom (Default model)

Number of distinct sample moments:	231
Number of distinct parameters to be estimated:	79
Degrees of freedom (231 - 79):	152

Result (Default model)
The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 22 additional constraints.

初次接触amos，想使用结构方程模型分析问卷。多次尝试，设置残差或是潜变量到观测值之间路径的量纲都没有效果。
