Hello Dr. Neale,
My name is Dr. Brandy Rutledge. I have attempted to duplicate the results from OpenMx in SAS for the first example in the Beginner’s Guide for Mx using the path model approach. I was able to duplicate everything except the -2 log likelihood (slightly lower) and the standardized standard errors (very different). I have done a little research on the web and found forums where the standard errors were being discussed a few years ago (2009). I am assuming that these issues have already been fixed. Do you know why the standardized standard errors in SAS using Proc Calis would be different from those that are produced by OpenMx?
Here is my SAS code for the first example in the Beginner’s Guide:
proc calis data=mxtest nobs=500;
Attached are the results from running this model.
Thank you in advance,
Dr. Brandy Rutledge
