Example 6.16 (two-part growth model) in the user's guide recommends fixing growth factor covariances to zero. What would you recommend if adding a quadratic factor? For example: iu su qu | bin1@0 bin2@.1 bin3@.2 bin4@.3; iy sy qy | cont1@0 cont2@.1 cont3@.2 cont4@.3; su-qu@0; iu WITH sy-qy@0; |

This is not a recommendation. It is a way to reduce the number of dimensions of integration from three to one. |
