Can Package SEM do mean structural analysis?
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.

Dear Mitsuo, My intention in writing the sem package was to provide a basic structural-equation facility for R. I haven't made explicit provision for models with means, but it might be possible to fit such models by using the raw sums-of-squares-and-products matrix among the observed variables (perhaps divided by n) as input. It might be necessary to make small modifications to degrees of freedom, etc.
