Dear Dr. Muthén, I am running a mediation analysis in LGCM framework. I wonder whether bootstrap with CI for the mediation effect is available for categorical outcomes using ML(R) estimator? Many thanks in advance, Caiyan |

Mplus Version 7.2 added bootstrap with numerical integration - which is what ML(R) calls for with categorical outcomes. |

There is a follow-up question that I want to ask. How to use model constraint command to specify and test the indirect effect when there are multiple pathways from X to the mediator? More specifically, in multiple growth process where growth factors in latent growth curve models are used as x(i1,s1) and mediator(i2,s2). MODEL: ...snip.. i2 on i1; s2 on s1; outcome on i2; ...snip... |

You simply have several a*b parts, one for each X and M. They can be added up for a total indirect effect. |
