RE: [NMusers] Using evid 0 before dosing

Hi Carlos,

It is commonly used. For most datasets, there will be at least one
observation that occurs before dosing to estimate the baseline value, and in
almost every scenario, the modeling dataset should mirror the real world
actions. So, there is no issue with it, and usually you will have an EVID=0
before the first dose.

Thanks,

Bill

Dear NMUsers,

I would like advice in the best practice to use evid 0 before dosing, which
is to say an observation just before a dosing (*to estimate the value in
that compartment just before dosing event).

Thank you,

Carlos,
