Hi Matts,
The easiest way to assess is when one of two endpoints is modeled directly
(TTE, logistic regression) as often is the case, than look at the Y value for
those endpoints, as reported in

Thanks all for input!
Maria, is this implemented in PsN by any chance?
Best,

Hi Jakob,
You are right. I guess the next best solution is to get information
from a direct calculation of the likelihood at each point. It won't
match the OBJI directly since it does not include the contribution
from the individual eta hessians.
There is a phi() function in NONMEM that can
Hi Matt,
That would work in case you had one subset of subjects with observations of one
endpoint, and another subset of subjects with observations of a different
endpoint - e.g. one study with only PK samples and another study with only PD
samples.
But in such a setting there would not be
Hi Matts,
The easiest way to assess is when one of two endpoints is modeled
directly (TTE, logistic regression) as often is the case, than look at
the Y value for those endpoints, as reported in the PRED variable. The
sum of those values is the ofv, or proportional to it, for that
particular
Hi Matts,
You can use the table item OBJI and sum over each ID to get any subset you
want.
