Can't you just explain that r2 is not a good measurement for goodness of =
fit for these types of models?

Does anyone have any reference for "typical" R^2 for pk/pd =
relationships. I have an analysis with an R^2 of 0.13 (highly =
significant), and the sponsor is unimpressed - thinking that an R^2 =
should be > 0.9 - apparently like it was in physics class.
