Missing CIs - How to get them?

Hi all,

When I ran the univariate or bivariate scripts for some of my variables, I often get NA for some of the CIs requested, followed by this line: "Investigate missing CIs with the detail output in MxComputeConfidenceInterval "

I would like to know what causes the missing CIs and what can I do to get the missing CIs? I'm not sure if I understand what arguments to put in the MxComputeConfidenceInterval.

Thank you very much for the help!

Best Regards,
Yi Ting

CIs

After mxRun, you can find the diagnostics in model$compute$steps$CI$output$detail Typically, the reason you get NAs is because your model isn't sufficiently identified.

summary with verbose=T

If you're running version 2.2.x, I think you should be able to see the detailed CI output if you do something like summary(myFittedModel,verbose=T).
