Hello,

I am running 1dSEM analyses to determine path coefficients in a network of 15 ROIs. My goal is to determine the best model in two groups, and compare how the models are different. I have a few questions about this analysis.

1) Do I simply compare the path coefficients between groups? Is there a statistical way to compare coefficients between groups?
2) When computing models, the cost, chisq, AIC, and parsimonious fit index are outputted. Should I be interpretting these in some way?
3) What is the typical computation time for this analysis?

I have been using the AFNI website to learn to run this simulation (http://afni.nimh.nih.gov/sscc/gangc/PathAna.html), and am uncertain where to find the answers to these questions. Is this the best code to run to answer my questions? Or is there something else that may be useful?

Thanks!
Derek
