求助大神！！！AMOS分析总是出现“The model is probably unidentified”！！

本帖最后由 哇哇小太阳 于 2013-7-23 08:36 编辑 作为初学者，硕士论文在使用AMOS进行结构方程路径分析时，结果一直出现下列的问题,而且好多变量之间Regression Weights项的输出值都是unidentified！！，请问这个是怎么回事啊？怎么解决啊？求大神帮忙！！！！！ Notes for Model (Default model) Computation of degrees of freedom (Default model) Number of distinct sample moments:990Number of distinct parameters to be estimated:118Degrees of freedom (990 - 118):872 Result (Default model) The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 12 additional constraints. 论文的初步模型图如下：
