Hi, Hi, I am running a categorical ESEM with 4 factors and 17 indicators. However, I received the following error message: THE LATENT VARIABLE COVARIANCE MATRIX (PSI) IS NOT POSITIVE DEFINITE. THIS COULD INDICATE A NEGATIVE VARIANCE/RESIDUAL VARIANCE FOR A LATENT VARIABLE, A CORRELATION GREATER OR EQUAL TO ONE BETWEEN TWO LATENT VARIABLES, OR A LINEAR DEPENDENCY AMONG MORE THAN TWO LATENT VARIABLES. CHECK THE TECH4 OUTPUT FOR MORE INFORMATION. PROBLEM INVOLVING VARIABLE V10. I have examined the correlations using TECH4 and the correlation between f3 and V10 is more than 1. Furthermore, V10 loads the highest onto f3 and V10 only has 3 categories. Are my results valid or do I need to respecify my model? What can I do to correct this? |

When two factor correlate greater than one, the model is inadmissible. You need to change the model. |

Hi Linda, Thanks for your prompt reply. I understand that model respecification is needed when the factors correlate more than 1. However, in this case, it is a factor-indicator correlation. Will this still apply? |

I would need to see the output because this does not make sense for the message. Please send the output and your license number to support@statmodel.com. |

Hi, I am experiencing the same problem described above: a factor-indicator correlation more than 1. Any advise for how to solve it? Thanks. |
