Dear NMus
> Dear NMusers,
I am using a dual absorption model as follows (The dose is split into 2
fractions and the splitting fraction, THETA(.), is an estimated parameter in
the model):
TPH = LOG(THETA(.)/(1-THETA(.)))
TH = EXP(TPH+ETA(.))/(1+EXP(TPH+ETA(.)))
F2 = TH
F1 = 1-TH
However, upon prolonge
