Re: inclusion of covariates with $PRIOR
Dear Anna,
Just to answer quickly on the question directed to me: Yes, you understood it
correctly.
To implement this in practice, since your NONMEM dataset only includes one
level for the covariate (all subjects have the same covariate value), you will
need to make a small addition to the SCM configuration file.
Lets assume DIS=1 is the covariate, where 1 codes for a new indication (which
was not present in the legacy data used to generate the prior), or a new
subpopulation, e.g. children/adolescents, where only adults where present in
the legacy data.
You would then need to add this to the scm configuration file:
[code]
*:DIS-2=PARCOV=(1+THETA(1))
Other than that, it is also a little tricky to generate the NONMEM control
stream with NWPRI on all parameters (of the base model).
PsN has an automatic function for generating this code (option to
update_inits), but it may be good to check manually.
Best regards
Jakob
