Subject: Re: Confirmatory Factor Analysis - CALIS (need assistance)
Original query follows reply.
Larry Hatcher's book, A step-by-step approach to using the SAS System for
Factor Analysis and Structural Equation Modeling, has several chapters on how
to set up various kinds of PROC CALIS analyses. Well worth having if you're
unsure of syntax.
