An error occurred while attempting to fit the model .<br>
The sample moment matrix is not positive definite . It could fail to be positive definite for any of the following reasons :<br>
1. The sample covariance matrix or the sample correlation matrix contains a data entry error .2. The observed variables are linearly dependent ( perhaps because the sample size is too small ).<br>
3. The sample covariance matrix or sample correlation matrix was computed from incomplete data using the method of ' pairwise deletion '.<br>
4. The sample correlation matrix contains correlation coefficients other than product moment correlations ( such as tetrachoric correlations ).<br>
For maximum likelihood estimation only , it may be appropriate to check " Allow non - positive definite sample covariance matrices " in the " Analysis Properties " window , or to use the NonPositive method .<br>
