TCALIS and CALIS Procedures

In SAS 9.2, the newly developed TCALIS procedure serves as an enhanced version of the older CALIS procedure. The TCALIS procedure has most of the capabilities of the CALIS procedure. In addition, it has some new capabilities that are not available in PROC CALIS. These new capabilities include multiple-group analysis, mean structures analysis, and a whole spectrum of modeling languages, among others. See Chapter 88, The TCALIS Procedure, for more details about the new features available in PROC TCALIS. In this chapter, statistical analyses in the examples are done using PROC TCALIS.
