Recently I'm working with Structural Equation Model (SEM). I have 3 latent variables and 12 manifests variables. Manifest variables were measured using ordinal scale. I used WLS method and off course with asymptotic covariance matrix as input. But when I run the code, fatal error produced with this message "The number of variables in the matrix to be analyzed exceeds the number of variables used to compute the Asymtotic Covariance Matrix". Can anyone help?
