Irregular dosing time

From: Min Dong Date: October 17, 2011 technical Source: mail-archive.com
Hi, NMusers; I have a data set with steady state multiple dose administration at every 12 hours. However, many of the dosing intervals are not exactly 12 hours, but have some delay. Below is an example of my data set (one TIME point is 60.9 instead of 60). I am using SS=1 and II=12 to describe the multiple SS doses. But for those time points with small delay, should I just ignore the time different and still use II=12? Is this going to affect my result? Or should something else to put in with SS and II? Thank you very much for your help.
