Please see my comments inserted below about the values of IPRED,W, etc.
for each type of error model

I hope the modeling goes well.

For CCV error model
IPRED=F
W=IPRED
Y=IPRED+W*ERR(1)

For LOG error model
IPRED=LOG(F)
W=1
Y=IPRED+W*ERR(1)

For additive error model
IPRED=F
W=1
Y=IPRED+W*ERR(1)

For additive + CCV error model
IPRED=F
W=SQRT(IPRED**2*SIGMA(1,1) + SIGMA(2,2))
Y=F + F*EPS(1)+EPS(2)

The following is true for all of the above models
IRES=DV-IPRED
IWRES=IRES/W
