My sample number was not sufficient and I also missed the covariance in the model.

Thanks to list for their suggestions.

Hello,

I am trying to run a path analysis with AMOS but I am getting the error
message:

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.

The message tells me to allow non-positive values for the matrix, I did so,
but still I am getting the error message

Could anyone please let me know where am I going wrong. It would really be
of great help.
