Estimated LV variances negative for first order factor (with two factors predicting a second order factor)

Hi Terence, That is my mistake. I used the colon as a short hand. But the actual model is below: mode

Heywood case with negative variance and calculation of CI with multiple imputations

Sorry for the confusion. Using cfa() I get nonconvergence. Using lavaan() I just get the heywood case

Please help me. Can I use a vcv matrix of factor scores as input to lavaan?

I have a covariance matrix from factor scores and I want to use that as input for my analysis.
