Dear community,
I trust you are doing well. Thank you very much for your immense work in structural equation modelling. I'm contacting you because I'm currently working on a research project that involves implementing a two-step structural equation model.
I got an error when I implemented the command to run the first-stage model (I've attached the document). From here, I do not particularly understand how to proceed. I have attached the codes and the data to aid you. I would be grateful if you could help me identify the error and, if convenient, with the right codes.
Once again, thank you very much, and I look forward to your response.
Kindest Regards,
There are errors in the data, such as correlation coefficients with minimum and maximum values of -550 and 1.188, respectively (see the end of the outputs), which are clearly invalid.
Dear Mike,
Thank you for the prompt response. Your answer helped helped. I have one more concern: Is it problematic if the TSSEM estimation returns a CFI of 0.265?
Thank you once again.
Regards

It is very strange that the CFI is so bad, especially for a mediation model. There is probably something wrong in your model or data.
Hi Mike,
Thank you for your response. Can you please give me any pointers as to where I can look to rectify this?
It is hard to tell. One common issue is that you forget to allow the predictors correlated. This will make the model fit terribly bad.
