Goodness of fit after factor analysis

[Giorgio Piccitto]

Dear Stata users, I am struggling with getting the goodness of fit statistics after a factor analysis.

I've found on the Stata manual the command - estat gof, (options) -, but it does not work after the command - factor - (Stata says: invalid subcommand gof).

DO you have any clue on how get these statistics after factor analysis?

Thanks a lot in advance.

Best, G.

The postestimation - estat gof - is not available after factor analysis.

Shall you test "sampling adequacy", you may wish to try this:

estat kmo

Also see sem (or gsem) for confirmatory factor analysis for which model fit statistics is very prominent - in contrast to EFA where I have never seen some kind of fit statistic reported.

Dear all,
thank you for your responses.

Actually, I would like to have a look at RMSEA and SRMR. I realized an alaysis that it is not strictly explorative (I tested my hypothesis), but I used the command - factor -.

As far as you know, is there any way to look at those indices?

Thanks a lot, G.

Why do you not use sem? factor is for exploratory factor analysis and not designed to test hypothesis. It strikes me as much simpler to just use the tool developed for your purposes.
