Coding RATE or II at SS

Dear nmusers, I met a problem when I was coding my data. Only one observation is available at steady state for an orally administrated drug. The drug was given in a constant dose weekly (but it is different from dose to dose within each day). I thought it is easy to code the constant dose. I assumed that II=168 hr(24x7). An example is given below: TIME AMT RATE DV CMT MDV SS II EVID 12 13.5 … 0 1 1 1 168 1 12.01 0 …. 16.2 2 0 0 0 0 Does RATE item takes any value>1 ?? Can anyone help me? other codes are welcome Regards Kalilo ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
