WLS versus robust WLS (i.e. WLSMV)... |

Hello, I'm running a SEM model where one latent variable is regressed on four latent variables. All indicators are categorical and the sample comprise about 35 000 cases. In Flora & Curran (2004) it is shown that WLSMV perform better than WLS in small to moderate samples. Will WLSMV outperform WLS in large samples (35 000), are they about equally accurate, or will WLS outperform WLSMV in samples of that size? Do you know of any simulation studies looking into this? |

I don't know about studies of that. I would guess that the two estimators perform about the same, although I worry about WLS with many variables. |

hi is there any reference talks about SEM methods WLS,DWLS,WLSMV and so on by details with functions. many thanks |
