Dear Dr. Muthen,
I am analyzing a latent growth model with 3 predictors to predict latent growth factors (intercept and slope). I am interested in the interactions between one IV a and the other two IVs, b and c. However, the uncorrected correlations between a and b, and a and c are .58 and .41 respectively. So I am worried about the potential problem of multicollinearity. How can I test that in LGM? Do you think the correlations are too high?
