Question regarding Calculation Process in $DES BLOCK
Hi,
I have a question about calculation process in $DES block.
Suppose I have 2 subjects, subject 1 has time point from 0-4hr, subject 2
has time point from 0-5hr.
Suppose I have NONMEM codes as follows:
$DES
DDT1=T
DADT(1)=-Kin*A(1)
When I output DDT1, the table will be:
Subject Time (hr) DDT1 1 0 4??? 1 1 1 1 2 2 1 3 3 1 4 4 2 0 5??? 2
1 1 2 2 2 2 3 3 2 4 4 2 5 5
Why the DDT1 for subject 1 at first time point is 4 and subject 2 at first
time point is 5? Why it holds the last time point value of each subject?
Thank you.
