StdYX greater than 1 leads residual v... PreviousNext

What is the problem that StdYX exceeds one?
Does that matter?

If StdYX (or Std) is greater than 1, e.g.,1.020, the residual variance will be -0.040. And R-Square is undefined. Following that there is 0.10400E+01. Should I use 0.10400E+01. as R-Square?

If this is a 1-factor model you have an inadmissible solution (since variances should be positive) and you would want to modify your model.

This is five-factor model

This may be a sign that the factor covariance matrix is not positive definite as it should be. For example, check for correlations greater than 1. However, for a fuller treatment of the topic of standardized coefficients greater than 1, see Joreskog's writing at

Try and go to Karl's corner. Perhaps they have changed the link.
