Minimization unsuccessful.
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 correlation matrix contains a data entry error 2. The observed variables are linearly dependent 3. The sample covariance matrix was computed from incomplete data using the method pairwise deletion 4. The sample correlation matrix contains correlation coefficients other than product moment correlations. NOTE :
N = 150
- Number of distinct sample moments: 300
- Number of distinct parameters to be estimated: 58
- Degrees of freedom (300 - 58): 242
