How to Scale a Multiple Groups Factor Analysis

There's no existing readily available analytic method that allows us not only to numerically evaluate that based on our sample data, but imagine the types of theoretical questions that this opens. It's amazing to see because in your mind's eye an x, y plot where x is age and y is the covariance between two factors, you can have a nonlinear relation that tracks increases in age with the model implied difference in the magnitude of the latent factors. That's absolutely right. In this multi-dimensional setting, it's particularly well suited to questions like the differentiation of factors over time, or what I think sometimes we observe in our age set, which is the de-differentiation hypothesis of cognitive
