proc calis

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.
