Hello,
I am trying to run a CFA for a factor structure developed from the EFA of a measure from a previous study. When I input the factor structure information into my code, I receive an error message indicating that the fit statistics could not be computed. Please see the error message below. Can you provide advice on how to fix this problem? This code has worked for my CFA runs with other factor structures using this same data set.
Thank you for your guidance.
