First I'm so happy that this group has written SEM software for R - Mplus is just way out of my budget!! Second I'm sort of new to this stuff, so I have a few beginner sorts of questions and I hope you'll bear with me - sorry.
I've never really understood modeling means in SEM. I know how it's done in OpenMx after reading through Dr. Boker's course notes, but I just don't understand exactly how the means are being estimated and why one would want to estimate them. I can't find any reference to this in any texts, so I would love some help or a point in the right direction.
Thanks so much!!
P.S. I can't seem to upload my picture to my account - I think there's a problem - something about it not being able to write the file to the correct folder? Thanks!!
