An error occurred while attempting to fit the model.

The sample moment matrix is not positive definite. It could fail to be positive definite for any of the following reasons:

1. The sample covariance matrix or the sample correlation matrix contains a date entry error.

2. The observed variables are linearly dependent (perhaps because the sample size is too small).

3. The sample covariance matrix or sample correlation matrix was computed form incomplete data using the method of

“pairwise deletion”.

4. The sample correlation matrix contains correlation coefficients other than product moment correlations (such as tetrachoric correlations).

For maximum likelihood estimation only, it maybe appropriate to check “allow non-positive definite sample covariance matrices” in the “Analysis Properties” window, or to use the non-positive method.

amos的意思是模型无法收敛犯了以下的错误之1
1.如果您的数据为raw data,那就不是这个
2.观察变量线性相依:根据个人经验,这个最可能,把所有的变量用spss跑相关,看有没有相关为1的变量,删除
3.这表示资料有遗漏值,但一般不是这个原因
4.跟第1修一样
