SEM- Modification indices

[Ellen Van Loo]

Hi,
I am working an a SEM model in STATA.
I obtain results.

However, when asking for the Modification indices with the command: "estat mindices", I receive an empty table such as shown below.
Can anyone advice me what I need to do to get values for the MI in the table instead of empty cells?

Thanks in advance,
Ellen

First off, it would be a lot easier to read if you used code tags; see point 12 of the FAQ.

Beyond that, it would help if we saw more of the code and output. It is hard to assess just this little piece in isolation.

What was the model chi square and DF? If it was a fully saturated model and the chi square was 0 then there wouldn't be any ways to improve the fit.

Dear Richard Williams,

Thanks for your reply and sorry for not being more specific.
Below I have included my syntax as well as the chi square and DF as well as the rest of the output.
I hope this provides the information you need.
Thanks in advance for your suggestions,
Ellen

Thanks. Note that the output can also be posted using code tags, which would make it far easier to read. You may still have time to edit your posts and add the tags.

[Marcos Almeida]

Hello Ellen,

I'll try to hazard a guess.

You "ideally" needed a low chi-square after the LR test, instead, far from that, you got an enormous value, leading to a tiny p. I fear such a "situation" indicates a severe deficiency in the model: it may not be reflecting well the complex patterns of covariations.

I'm rather curious on what the output of - estat gof, stats(all) - , as well as - estat eqgof - and - estat teffects, standardized - would provide...

Best,

Marcos

[Ellen Van Loo]

Dear Marcos,
Thanks for your answer.

Below you can find the output for estat gof.
estat eqgof and estat teffects are not shown here as this model is a CFA.
When including also the path model, I get the same problems with the MI. But since I also get this problem without the path models (only CFA), I think it must be related with something with the CFA.
Any suggestions are welcome.
Thanks in advance,
Ellen

I wonder if it might be a display problem? Probably not, but after estat mindices, try

mat list r(mindices)

[Marcos Almeida]

Your RMSEA, SRMR and CFI seem to be reasonably good. I cannot envisage what might have happened. A thing that still bothers me is the high value of the chi-squared for the LR test.

[Clyde Schechter]

At 2,783 observations, even if the model is pretty well specified in other respects, the LR chi square is pretty sensitive to departures from multivariate normality. In fact, it is this sensitivity that, historically, motivated the development of the other fit statistics.

I have no ideas about the original poster's question, however.

[Joe Schmo]

I had the same problem and even though this is an old thread I wanted to post the solution to others.

 estat mindices

uses an algorithm to save time. There is an undocumented option,

 estat mindices, slow

that takes much, much longer but will resolve this issue.

[Alicia Lynch]

Thanks so much for following up with this post, Joe Schmo. I was having the exact problem described above and adding ", slow" worked for me. Took a long time, but worked.

[Benjamin Gh]

I have the same problem! Even using "Slow" didn't help. Any advice?

[Martin Ruth]

Hi there,
I'm facing the same issue.

estat mindices, slow

results in the same empty table.

Has anybody solved this issues in the meantime?

My sample size is ~650; find my goodness-of-fit statistics below.

Thanks a lot in advance!

Dear Stata users:

Has this problem with Mindices been finally resolved? I have the same problem. Would someone help?
