I'd like to investigate if I can do CFA or Rasch model using PROC CALIS.
unt.edu/rss/class/Jon/SAS_SC/SEM/SAS_Module8_SEM.htm
I made this up.
PROC CALIS COVARIANCE CORR RESIDUAL MODIFICATION data=one;

risk_1n= F1 + E1,
risk_2n = F1 + E2,
risk_3n= F1 + E3,

risk_6n= F2 + E6;
STD
F1 = 1,
F2 = 1,
E1-E6 = VARE1-VARE6;

F1 F2 = CF1F2;

Why do switching of values in a dummy variable and the use of class statement in PROC LOGISTIC change the coefficients in logistic regression?
(1) and (2) produce the same results. (3) and (4) produce the same results.
(1)
proc logistic data=here.asdf descending ;
model college= boy ;
run;
(2)
proc logistic data=here.asdf descending ;
class girl;
model college= girl ;
run;
(3)
proc logistic data=here.asdf descending ;
model college= girl;
run;
(4)
proc logistic data=here.asdf descending ;
class boy;
model college= boy ;
run;
