Subject: Can Package SEM do mean structural analysis?
In-Reply-To: <5.1.0.14.2.20030524103328.01e9e310@mcmail.cis.mcmaster.ca>
Dear John:
I can make it on your suggestion in mean structural analysis.
I appreciate so much and love your package sem.
I hope your package sem will be extended in near future.
