Re: AW: Problem to implement a change in transfer rate after event during measurement period

Hi Andreas In this case, the code I am familiar with under $PK is: MTIME(1)=THETA(..) TK120=THETA(..) ; rate constant until MTIME TK121=THETA(..) ; rate constant after MTIME K12=TK120*(1-MPAST(1)) + TK121*MPAST(1) ; MPAST(1) is 0 until MTIME(1) whereupon it becomes 1 I am not sure what MTDIFF does, but I have not observed any difference when I set it to 1 in the code. Hope this helps this time :-)) Emmanuel >>> Steingötter Andreas 07/28/10 3:53 PM >>> Emmanuel, Thanks for your suggestions. I played around a bit, but it becomes obvious that the actual event is reflected in the data at some unknown later point in time which I cannot predict and which also depends on the Individual. Therefore I reckon I need to model an event time using MTIME instead of your much easier approaches.
