Problems with CFA demo?

Am I doing something wrong?

I tried running the CFA demo, but got this error message:

A latent variable 'G' was created.

Running CFA with 15 parameters

?umxSummary showEstimates='raw|std', digits, report= 'html', filter= 'NS' & more

Running Saturated CFA with 20 parameters

Warning incurred trying to run model

In model 'Saturated CFA' Optimizer returned a non-zero status code 6. The model does not satisfy the first-order optimality conditions to the required accuracy, and no improved point for the merit function could be found during the final linesearch (Mx status RED)

Hi Dorothy

Thanks for the comment. That's a warning, not an error. I'm in the process of adding "Just a friendly warning but..." to warnings wherever I can to help make this distinction :-)

Switching optimizer might help.

umxsetoptimizer()

Or re-run the model

m1 = mxTryHardOrdinal(m1)

Thanks. I appreciate the info, but this is the first e.g. in your paper, and if you don't actually get the output that is described in the paper, it is offputting to beginners and people may give up - which would be a shame.
