Re: [NMusers] Is there an easy way to get PRED from NONMEM when objective function instead of error model is specified?

To get PRED, nonmem runs the model with all ETAs fixed to zero. COMACT
variable is equal to 1 at this step. So if IPRED is the concentration
predictions, then the line:

   IF(COMACT.EQ.1) PREDI=IPRED

will give you concentration predictions when all ETAs are equal to zero
(that is PRED). This is also convenient to get PRED for BQL observations
(when M3 is used)
