Hi all,

When building a scale, I used component transformation matrix as confirmation of orthogonality between the factors, and it came up with a rather high value. Trying to argue for orthogonality, I turned to the factor scores coefficient matrix as the scores are standardized values, and should tell me if factors are right angled vectors right?But when running af a covariance display, there seemed to be a trivial value for covariance but nevertheless it shows. Why is that? To me very low coefficients for covariance between the two toploading variables in each factor should mean the factors are uncorrelated and thus orthogonal or?
