I am performing an exploratory structural equation modeling with categorical variables, but unfortunately, 2 of my loadings are up to 1 or very close to 1. I suppose I have negative residual variance, but I'm unable to fix the problem. I know I have to switch to theta parameterization, test if the variance if significant, and fix it to 0 if not, but I don't know how to do. Can you help me?
I am trying to save factor scores for an ESEM using the code below. However, I received the message, "FACTOR SCORES COULD NOT BE COMPUTED. AT LEAST ONE OF THE RESIDUAL VARIANCES FOR THE CATEGORICAL VARIABLES IS NOT POSITIVE." The problem variable is Med_YN_Days.
