Good morning. The default for running an EFA at two time points with factor loading invariance (as in example 5.26) is for the factor variances at time one to be fixed at 1. How do I allow the factor variances at time 1 to be free (while maintaining free variances for time 2 factors)?

Thank you!

In EFA, the metric of the factors are set by fixing the factor variance to one. It must be fixed at one in one group because of this.
