• For PROC CALIS syntax, refer to the CALIS chapter in the SAS/STAT^® User's Guide.
• For background information on structural equation modeling with PROC CALIS and comparisons of PROC CALIS with other SAS/STAT procedures, see "Introduction to Structural Equation Modeling with Latent Variables" in the "Introductions" section of the SAS/STAT^® User's Guide. It is recommended that you read this chapter before running PROC CALIS for the first time.

  This is a good beginning book for structural equation modeling.
