Re: Two sequential absorption processes
Hi Liu,
One reason why you don't get the expected result with your current code
is that you probably confuse TIME (which is the time of the current
record) and T (which is the "running" time in the $DES block).

... here, you should probably use T instead of TIME.
However, I'd vote for "putting the model into the data" as Luann
suggested by using two dose records; one for the zero-order and one for
the first order absorption.
Kind regards,
