RE: Simultaneous vs sequential for modeling parent AND metabolites in pop PK
Hello Alan
I have used a sequential approach in the past as the model was more
stable with lesser run time.

Subject: [NMusers] Simultaneous vs sequential for modeling parent AND
metabolites in pop PK
Dear All,
I know this is an old topic but would like to see the statistics.
When you have to develop a pop PK model for both parent and active
metabolites, which approach do you prefer or have you used most:
simultaneous or sequential? Which way do you think is more scientific? I
heard comments saying that the simultaneous approach is not scientific.
Thanks,
Alan
