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? Thank you very much in advance! |

Those correlations don't sound unusually high to me. I would see a regression book to see what it says about multicollinearity. |

Thanks for the response. Does Mplus provide any diagnosis for this problem? |
