hi
i want to estimate parameters of sem by using weighted least square method but i have some question through the following sas program:
1- i want to write my own weight matrix how??
2- how can i write initial values?
3- how can i change link function here?
proc calis nobs=1000 data=MVO method=WLS;
var X1-X10;
lineqs
X1 = a1*F1+e1,
X2 = F1+e2,
X3 = F1+e3,
X4 = F1+e4,
X5 = a5*F2+e5,
X6 = F2+e6,
X7 = a7*F3+e7,
X8 = F3+e8,
X9 = a9*F4+e9,
X10 = F4+e10,
F2 = F1+d1,
F3 = F1+d2;
std
e1-e10 = The1-The10,
d1-d2 = psi1-psi2;
cov
e3 e5 = The11,
e4 e6 = The12;
weight;
run;
thanks in advance
you may want to repost this to the SAS Statistical Procedures forum, you'll get more CALIS users there.
thanks alot
More CALIS users? Where? I haven't seen any around here yet...
