1. Confirmatory Factor Analysis
SAS Calis

2. Download the Data CFA-Wisc.xls on my StatData page\
These are the same data earlier analyzed with AMOS

3. Verbal IQ
Proc Calis cov pAll; var Info Comp Arith Simil Vocab Digit PictComp PictArang Block Object Coding;
LINEQS
Info = v1 F_Verbal + e1,
Comp = v2 F_Verbal + e2,
Arith = v3 F_Verbal + e3,
Simil = v4 F_Verbal + e4,
Vocab = v5 F_Verbal + e5,
Digit = v6 F_Verbal + e6,

4. Performance IQ PictComp = p1 F_Perform + e7,
PictArang = p2 F_Perform + e8,
Block = p3 F_Perform + e9,
Object = p4 F_Perform + e10,
Coding = p5 F_Perform + e11;

5. Variances & Covariances
STD
F_Verbal F_Perform = ,
e1-e11 = e_var1-e_var11;
Factor variances fixed at 1 
COV
F_Verbal F_Perform = phi;
run;
phi is the covariance between factors, to be estimated.

6. The Output Compare the output to that obtained from AMOS.
Same solution. 
