If you put in a zero, it's not a dose...
One is usually used as a "unit dose", a bioavailabity term can be modeled
to account for scaling the dose to accomodate to observed dependent variable
values.

Subject: [NMusers] Dummy dose
Dear NMusers:
Can anyone give me some suggestions on how to use dummy dose and dummy
observation? I cannot find a clear explanation on how to use it. I see in a
thread discussion that a single unit (normally '1') should be put in, but
why not using "0" or a small number (such as 0.001)? Don't you need to worry
that '1' will create some artifact if the real dose is close to '1'?
Thank you very much in advance for your time.
Regards,
Siwei
