In my measurement model, I have several latent variables for which there are only 2 indicators. When running the CFA, do I need to constrain these indicators somehow? Someone mentioned something to me about the indicators being "equal"? I don't know what this means, nor do I know how to do it. HELP! |

No constraints needed as long as the factor which has those 2 indicators is correlated with other factors. Indicators being equal might refer to holding loadings equal, that is fixed at one for both - but not needed here. |

OK, when running the CFA, do I run all of the factor loadings simultaneously? E.g., MODEL: F1 BY y1, y4, y10; F2 BY y2, y3, y5; F3 BY y6, y7; F4 BY y8, f9; Or do I run each Latent variable separately? e.g., F1 THEN F2 THEN F3 THEN F4 |

If your model has more than one factor, you would run all of the factors simultaneously. You may want to listen to the Topic 1 and 2 course videos that are on the website. |
