Dear AFNI people,
I recently run into your 1dSEM tcsh script and played around with it for a while. I ran the tree growth search model (didnt really have a particular model, so I decided to let 1dSEM to find the best model) using 3 roi's and it gave me path coefficients around 8 and -8. Is this possible? Also, what does cost and Akaike's Information Criterion mean? how can I get root mean square error of approximation (RMSEA), and Comparative Fit Index (CFI)? Sorry, but I'm new to all this. It seems that there is not much literature about 1dSEM and what is available is a little outdated.
Thanks
