Use of ADDL and II
Dear All,
I am modeling a repeated dosing study. Subjects were given twice daily doses
for 8 weeks and a number of samples were taken on the last day of dosing. There
were also sparse samples taken at weeks 2, 4, and 6. I want to use ADDL and II
for the dosing scheme. Can I lump all doses into one line or do I have to stop
the dosing record prior to each sample and re-start again? In other words, will
the following file structure work:
ID TIME AMT ADDL II DV
1 0 10 112 12 0
1 143 0 0 0 124
1 287 0 0 0 131
.
.
.
Or do I have to use the following:
ID TIME AMT ADDL II DV
1 0 10 14 12 0
1 143 0 0 0 124
1 144 10 14 12 0
1 287 0 0 0 131
.
.
.
Thank you in advance.
BP
