Dear Suzanne,

Your question is justified. It seems like experimental values over
128 mg/ml shows also low activity responce? In QSARs only excact values
for activity should be used, hence I prefer to exclude the compounds
which do not have these values. Of course, some discussion of the
reasons why there are compounds which shows low activity (in this case
there might also be some analytical problems, like low solubility etc).

With all the best,
Jarmo
