Herbert,

Thanks once more.

I see what you have done. Now I need to learn how to do this without
bothering you.

Too bad I can not send you the data that we have since Dec. 30, 2008.
What we are looking at is data that showed her in remission for a
while. Then the drug regimen she was on loosing its effectiveness
which resulted in a relapse and now a new treatment plan which is
getting the disease under control. After looking at the real data
for her disease we are hoping that the flat portion of the curve from
your model will truly extend. Should that be the case then we would
have a new situation where the readings vary randomly within the
normal range until this set of drugs loose their effectiveness.

Returning to your analyses for sheet 2 how did you compute Ao, t1/2,
k, and the b offset?

For the regression model the results are quite significant. I assume
you are fitting to the model from sheet2. Here again I need to figure
out what you setup and how you did it.

All help is really appreciated.

Paul
