<PROC CALIS> how to create a acceptable pathdiagram。

[Phoenix_LJ]

In the procedure Proc CALIS, is there a decent way to create resonable  pathdiagram for structural equations model.

I drew a diagram, but it looked so confusing!

You might want to use the PATHDIGRAM statement in PROC CALIS, which provides much more controls over the appearance of the path diagram.

Hope this helps,
