Description
Hi guys,
I hope you are very well.
I would like to inquire about the ABNORMAL_TERMINATION_IN_LNSRCH optimization error when performing the 5-item confirmatory factor analysis that is explained by one latent variable.
I have found this same issue in other libraries and in R, where they indicate that it can occur in functions where the surface is very flat, in fact if I evaluate these same items by exploratory factor analysis with one component, the factor loadings are very close to each other.
I can do something to avoid this?, What is your opinion of what is happening?, or I would really appreciate if you could tell me how I can justify it, since the study is intended to be a scientific publication.
I leave screenshots with part of the code and the versions I have installed.
Best regards.
Here i define my variables:

and then, the problem appears like this:
