Dear all,
I wanted to know if there is any shortcut in lavaan to indicate freely-estimated factor covariances among 20 latent factors (4 factors across 5 waves) without writing the syntax manually, when combined with orthogonal=T command?
I know that factor covariances are default in the cfa() function, but I also have "method" factors to accommodate reverse-keyed items and the correlated residuals of the same item(s) across five waves. I wanted to first use orthogonal=T command to restrict covariances among all factors in the model and then manually write syntax to indicate freely estimated covariances among the 20 "main" latent factors. But this would mean that I have to write a long syntax, which may be possible using a list-like shortcut?
Doing the opposite -- allowing freely-estimated covariances as per the default and then manually restrict covariances with the "method factors" -- would also require to write a long syntax.
Any suggestion would be very helpful.
Best regards,
Oliur
