Tech4 when setting variance to 1

Hello Linda and Bengt,

I am running a model in which my factor residual variances are constrained to 1 (all factors are endogenous). Is it ok to use the TECH4 command to estimate factor variances and covariances etc?

or do I need to reparameterize the model to identify the factor by setting a loading of at least one indicator to 1 so that I can estimate the variance of the factor?

Thank you!
